[-- Attachment #1 --] Hello, I have installed FreeBSD 5.3 on a Compaq Presario R3000. It has an AMD 64 bit processor. First, I am very grateful for all of the work done by Jung-uk Kim. If it were not for his work it would not have been possible for me to get my machine going under FreeBSD. Second, there appears to be a very serious performance issue with this machine. I have a program that I use for benchmarks which approximates a nonlinear PDE. It uses a 300x300 matrix which is relatively small so it does not require much in the way of swap or memory caching. When I run this program under freebsd it takes 234 seconds in user time (not real). I have CygWin installed on the windows slice and ran the exact same program. I have the 32 bit version of Windows XP. Under CygWin the program takes 155 seconds in user time. This is almost 33% better under MS windows and is a huge discrepancy! It seems clear that something isn't right on the machine. I have attached a copy of my kernel file. I have applied many of the patches so generously made available by Jung-uk Kim on this list. The times have remained consistent before and after all of updates. I have used RELENG_5 as the src-all tag in my cvsup,conf, Any pointers on what I can do to tune this machine would be very helpful. Has anybody come across this problem? By the way, I have used this same program to benchmark an opteron system. On that machine I installed FreeBSD 5.3 (generic kernel) and then installed gentoo (2.6.9 kernel). The times under both OS's were almost identical.
