My dev box runs Windows XP with an oldish intel core 2. It processes my rules in 13s, with a peak memory usage of about 600MB.

 

When I run the exact same code on my 64bit linux server with a quad 2.40Ghz Xeon, it takes 22s and uses a peak of 1.5Gb memory.

 

What on earth is going on here? I would expect it to run faster on the server and for the memory usage to be similar.

 

 

Cheers,
