Altought I have 2GB of RAM, I found a limit of 182 MWORDS under WinXP Home 32bits and 268 MWords under WinXP x64 (I have a dual boot). Any hints?
By the way, what can I do if I need more than 268 MWORDS? What about running PC GAMESS under linux version (32 or 64 bits)?

I am agrre, but this is for performance degradation or for other reason?
