I'd be surprised if the 'code' is intrinsically that much faster but as far as 32 bit O/S's go, Linux has a much smaller memory footprint and better swap handling (Windows swap space has to go through the filesystem but Linux has it's own swap partitions), so the difference in render times _may_ be due to the Windows render needing to use swap space when the Linux system didn't, or because the Windows render needed to use more swap space than the Linux render. On the one the one system I have that can dual boot in to XP (all my other systems are Linux only) I find that the XP system uses about 800Mb after booting (even after stopping a lot of unnecessary progs/accessories from loading) whereas Linux only occupies about 220Mb for code and data and will use any remaining ram for cache. I haven't got any 64 bit systems, so can't comment on the differences that might make. LeeE
