I decided to write GenPrime in C, Java, Perl, PHP, Python, and Ruby. I used essentially the same code in every language, adapted for that particular language's syntax. I chose to avoid any special performance tricks to give any language a special advantage (i.e. psyco for Python), just keeping to the most simple code possible.

The host machine is a MacBook Pro, 2.33GHz Intel Core 2 Duo. It's running Mac OS X 10.5.5 for these tests. I ran all the tests at the highest possible priority (process priority -20).

First of all, here's the various interpreter/compiler versions:
Code:
Alcarin:genprime steven$ make version gcc -v Using built-in specs. Target: i686-apple-darwin9 Configured with: /var/tmp/gcc/gcc-5488~2/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=i686-apple-darwin9 --with-arch=apple --with-tune=generic --host=i686-apple-darwin9 --target=i686-apple-darwin9 Thread model: posix gcc version 4.0.1 (Apple Inc. build 5488) java -version java version "1.5.0_16" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284) Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing) perl -v | grep built\ for This is perl, v5.8.8 built for darwin-2level php --version PHP 5.2.6 (cli) (built: Jul 17 2008 23:04:49) Copyright (c) 1997-2008 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies python --version Python 2.5.1 ruby --version ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]

And here are the timings.
Code:

So basically, the best to worst performance order is this:
C, Ruby, Java, PHP, Python, Perl.

Using Psyco on the Python version, the order would change to:
C, Ruby, Java, Python, PHP, Perl.

If you want the source for all the versions, it's all available in a [url=git://github.com/tycho/genprime.git]Git repository[/url] graciously hosted by github.com.

EDIT: Whoops, random incomplete sentence in there.

Added C++, C#, and Objective-C. I would be very interested if someone wrote one in a functional or purely functional language (Common Lisp, Haskell, etc).

Here's the added version information:
Code:

Added JavaScript implementation. This one is trickier than the others, because nearly every browser has its own implementation of JavaScript (which makes the timings vary wildly).

For this test, I'm using WebKit nightly (r38297):
Code:
genprime (JavaScript) Found 25000 primes in 0.158 seconds Found 50000 primes in 0.434 seconds Found 75000 primes in 0.785 seconds Found 100000 primes in 1.198 seconds Found 125000 primes in 1.662 seconds Found 150000 primes in 2.182 seconds Found 175000 primes in 2.737 seconds Found 200000 primes in 3.336 seconds Found 225000 primes in 3.965 seconds Found 250000 primes in 4.631 seconds
You'll note that I used a different test interval. That's because if a particular script takes too long, Safari decides to halt the JavaScript execution and ask the user if the script should be terminated. Unfortunately, halting the script also totally blows the timings. I decided to use power regression to predict what the results would be with a full run. Here's the prediction (r-squared is 0.9999898):
Code:
genprime (JavaScript) Found 50000 primes in 0.434 seconds Found 100000 primes in 1.203 seconds Found 150000 primes in 2.181 seconds Found 200000 primes in 3.328 seconds Found 250000 primes in 4.618 seconds Found 300000 primes in 6.036 seconds Found 350000 primes in 7.569 seconds Found 400000 primes in 9.208 seconds Found 450000 primes in 10.946 seconds Found 500000 primes in 12.778 seconds
Not bad for a JavaScript interpreter. Hell, it even beats Java, and Java's the prettier cousin!


EDIT:

I also tested on Safari's current release version (v3.1.2). The results weren't quite as invigorating:
Code:
genprime (JavaScript) Found 10000 primes in 0.284 seconds Found 20000 primes in 0.748 seconds Found 30000 primes in 1.339 seconds Found 40000 primes in 2.04 seconds Found 50000 primes in 2.821 seconds Found 60000 primes in 3.699 seconds Found 70000 primes in 4.619 seconds Found 80000 primes in 5.639 seconds Found 90000 primes in 6.696 seconds Found 100000 primes in 8.034 seconds
I had to use an even smaller interval, because Safari 3.1.2 doesn't use the new SquirrelFish Extreme engine that's in the WebKit nightlies. Okay, statistical projection time (r-squared: 0.9997743):
Code:
genprime (JavaScript) Found 50000 primes in 2.852 seconds Found 100000 primes in 7.787 seconds Found 150000 primes in 14.013 seconds Found 200000 primes in 21.261 seconds Found 250000 primes in 29.378 seconds Found 300000 primes in 38.261 seconds Found 350000 primes in 47.838 seconds Found 400000 primes in 58.050 seconds Found 450000 primes in 68.854 seconds Found 500000 primes in 80.211 seconds
Still not nearly as bad as PHP, Python, Perl, etc. But SquirrelFish is certainly less speedy than SquirrelFish Extreme!

Javascript also has ALOT less overhead. However that is interesting, perhaps try it on other browsers like opera, mozilla and ie. I think webkit uses a JIT for js.

I would write a copy in bf but its tentively limited to numbers up to 255 on a standard interpreter and restricted to the interpreter its run on. (I could work around this but that code is huge, and my sqrt routine still needs some work)

Here's Camino 1.6.4 (Mozilla's Mac-only browser). I would suspect that the results would be the same on Firefox, SeaMonkey, etc.
Code:
genprime (JavaScript) Found 10000 primes in 0.319 seconds Found 20000 primes in 0.889 seconds Found 30000 primes in 1.601 seconds Found 40000 primes in 2.437 seconds Found 50000 primes in 3.376 seconds Found 60000 primes in 4.412 seconds Found 70000 primes in 5.544 seconds Found 80000 primes in 6.744 seconds Found 90000 primes in 8.053 seconds Found 100000 primes in 9.41 seconds
Had to statistically predict this one too (r-squared: 0.99998968):
Code:
genprime (JavaScript) Found 50000 primes in 3.389 seconds Found 100000 primes in 9.370 seconds Found 150000 primes in 16.987 seconds Found 200000 primes in 25.908 seconds Found 250000 primes in 35.944 seconds Found 300000 primes in 46.969 seconds Found 350000 primes in 58.891 seconds Found 400000 primes in 71.638 seconds Found 450000 primes in 85.153 seconds Found 500000 primes in 99.390 seconds

I shudder to think of what IE would do.

I have IE6 on this machine (I call it the FailBox, because if anything will break, it'll break here).

I'll do a rendition for it.

Well, I've tested IE6 and IE7 now. They performed identically.
Code:
genprime (JavaScript) Found 10000 primes in 0.812 seconds Found 20000 primes in 2.172 seconds Found 30000 primes in 3.781 seconds Found 40000 primes in 5.641 seconds Found 50000 primes in 7.813 seconds Found 60000 primes in 10.141 seconds Found 70000 primes in 12.484 seconds Found 80000 primes in 15.125 seconds Found 90000 primes in 17.953 seconds Found 100000 primes in 20.844 seconds
And here's the power regression (r-squared: 0.99996127):
Code:
genprime (JavaScript) Found 50000 primes in 7.814 seconds Found 100000 primes in 20.731 seconds Found 150000 primes in 36.685 seconds Found 200000 primes in 54.999 seconds Found 250000 primes in 75.296 seconds Found 300000 primes in 97.327 seconds Found 350000 primes in 120.913 seconds Found 400000 primes in 145.917 seconds Found 450000 primes in 172.231 seconds Found 500000 primes in 199.766 seconds
Eeegh.

I'm going to try IE8 and Chrome in a bit. As well as Firefox (on Windows).

Here's Chrome v0.3.154.9:
Code:
genprime (JavaScript) Found 50000 primes in 0.305 seconds Found 100000 primes in 0.825 seconds Found 150000 primes in 1.475 seconds Found 200000 primes in 2.259 seconds Found 250000 primes in 3.142 seconds Found 300000 primes in 4.099 seconds Found 350000 primes in 5.131 seconds Found 400000 primes in 6.261 seconds Found 450000 primes in 7.473 seconds Found 500000 primes in 8.713 seconds
Looks like Chrome's JavaScript engine is indeed as good as is claimed. It beats WebKit (by a somewhat small margin which will no doubt close with time).

You can easily grab a copy of the Mac Opera and test it there, see how it preforms on thier ECMAScript engine (aparently Javascript just wasn't good enough). If you use dragonfly (built in developer tool), you might be able to run the full test on it.

See the 'C' example. Also, I don't intend to write a handcoded ASM one. I might take the compiled C one and hand-optimize it, though.

I ran your C# version on my comp and it ran alot faster( maybe mono is slower *shrugs* ).

I suspect Mono is indeed slower. I'm going to run it on Windows using Microsoft's C# compiler in a bit.

So apparently Ruby isn't as fast as I thought. I added some debugging output (shows the last prime calculated on each final iteration), and discovered that Ruby was thinking -every number- was prime. So yeah. Here are the new results:
Code:
genprime (C) Found 250000 primes in 2.03855 seconds (last was 3497861) Found 500000 primes in 5.69525 seconds (last was 7368787) Found 750000 primes in 10.32096 seconds (last was 11381621) Found 1000000 primes in 15.84383 seconds (last was 15485863) genprime (C LLVM) Found 250000 primes in 2.00452 seconds (last was 3497861) Found 500000 primes in 5.58073 seconds (last was 7368787) Found 750000 primes in 10.56258 seconds (last was 11381621) Found 1000000 primes in 16.97467 seconds (last was 15485863) genprime (C LLVM JIT) Found 250000 primes in 2.00863 seconds (last was 3497861) Found 500000 primes in 5.66369 seconds (last was 7368787) Found 750000 primes in 10.37664 seconds (last was 11381621) Found 1000000 primes in 15.89380 seconds (last was 15485863) genprime (C Clang/LLVM) Found 250000 primes in 1.95876 seconds (last was 3497861) Found 500000 primes in 5.45282 seconds (last was 7368787) Found 750000 primes in 10.05708 seconds (last was 11381621) Found 1000000 primes in 15.72205 seconds (last was 15485863) genprime (C Clang/LLVM JIT) Found 250000 primes in 2.47696 seconds (last was 3497861) Found 500000 primes in 7.08403 seconds (last was 7368787) Found 750000 primes in 11.12229 seconds (last was 11381621) Found 1000000 primes in 16.84753 seconds (last was 15485863) genprime (C++) Found 250000 primes in 2.01354 seconds (last was 3497861) Found 500000 primes in 5.62421 seconds (last was 7368787) Found 750000 primes in 10.20536 seconds (last was 11381621) Found 1000000 primes in 15.61217 seconds (last was 15485863) genprime (C#) Found 250000 primes in 10.84425 seconds (last was 3497861) Found 500000 primes in 41.89792 seconds (last was 7368787) Found 750000 primes in 99.06289 seconds (last was 11381621) Found 1000000 primes in 191.11001 seconds (last was 15485863) genprime (Java) Found 250000 primes in 8.12293 seconds (last was 3497861) Found 500000 primes in 25.88073 seconds (last was 7368787) Found 750000 primes in 41.94243 seconds (last was 11381621) Found 1000000 primes in 64.42176 seconds (last was 15485863) genprime (Objective-C) Found 250000 primes in 1.99582 seconds (last was 3497861) Found 500000 primes in 5.52849 seconds (last was 7368787) Found 750000 primes in 10.01903 seconds (last was 11381621) Found 1000000 primes in 15.39874 seconds (last was 15485863) genprime (Perl) Found 250000 primes in 57.16553 seconds (last was 3497861) Found 500000 primes in 163.05147 seconds (last was 7368787) Found 750000 primes in 296.21224 seconds (last was 11381621) Found 1000000 primes in 493.05088 seconds (last was 15485863) genprime (PHP) Found 250000 primes in 44.62868 seconds (last was 3497861) Found 500000 primes in 156.24447 seconds (last was 7368787) Found 750000 primes in 218.98360 seconds (last was 11381621) Found 1000000 primes in 339.03871 seconds (last was 15485863) genprime (Python) Found 250000 primes in 52.77145 seconds (last was 3497861) Found 500000 primes in 149.61378 seconds (last was 7368787) Found 750000 primes in 277.18452 seconds (last was 11381621) Found 1000000 primes in 431.14573 seconds (last was 15485863) genprime (Ruby) Found 250000 primes in 133.67173 seconds (last was 3497861) Found 500000 primes in 406.23774 seconds (last was 7368787) Found 750000 primes in 695.72089 seconds (last was 11381621) Found 1000000 primes in 1188.29837 seconds (last was 15485863)
Congratulations, Ruby! You now have the dubious honor of being the slowest scripting language at our disposal!
