Hi, As suggested by Xin LI, I request here. Please refer to: http://lists.freebsd.org/pipermail/freebsd-hackers/2006-February/015560.htm= l About further developments: - I'm working on dropping/undropping FPU and using mmx/xmm simd instructions. The code works fine (no PREEMPTION kernel), but mmx doesn't seem enough efficient so I think I need more work about them (I didn't try xmm simd instructions yet). - I planned to add some sysctl in order to enable/disable optimized copying functions You can get patch for FreeBSD-6.0 here: http://users.gufi.org/~rookie/fpu_overhaul.tar.gz and a patch for -current will be available ASAP (however they might be very poor changes since a lot of stable parts are modified). Thanks a lot, Attilio -- Peace can only be achieved by understanding - A. Einstein
