Fastnesses!

This is updated from my previous post. I now have three new servers to play with, so let's see how they go.

Linux

Kasumi, Ukyo and Shampoo are Xeon 3060s: dual-core 64-bit 2.4GHz
Akane and Nabiki are Opteron 170s: dual-core 64-bit 2.0GHz.
Ranma is an Athlon XP 3000+: single-core 32-bit 2.16GHz.
Martina is an Athlon XP 2800+: single-core 32-bit 2.08GHz.
Naga is an Athlon 64 3200+: single-core 64-bit 2.0GHz.
Namo was a P4 Celeron: single-core 32-bit 1.7GHz

Windows

Lina: Pentium 4 2.6GHz
Amelia: Core Duo 1.66GHz
Haruhi: Core 2 Duo 2.4GHz

Psyco

HaruhiCore 22.4GHz2.5 (Win)+Psyco0.0120.2730.5540.839

I'm not sure where the difference between the Linux and Windows versions comes from; I'm guessing that Psyco would still be using Python's string libraries, and they're compiled using a different (better) compiler on Windows, perhaps Intel's. I'm still using GCC 3.4.6 (which is what CentOS installs); I might be able to do better with GCC 4.1, and I'll probably try that at some point.

1 If you're playing... is this why I'm getting a "fruitcake" error when I go to blog.mu.nu instead of the logon screen? Just wondered.

2 Woops! It was related, yes. I changed the internal host names around to account for the new servers, and messed up the one being used by Movable Type.

Fixed now.

3 In your benchmark numbers, low scores are good?

4 Yep, all in seconds.

5 One thing I noticed - the string optimisations that make Python so effective for this sort of thing only appeared in 2.4. 2.3 exhibits the same sort of behaviour as IronPython - the "String" benchmark is about 600 times slower.
