Hello, I have been very impressed with my FreeBSD 6.2 install, I have nearly everything working but there are a few things which I need help with. The main problem is my HD performance, it is approx 6x slower than in windows XP, hopefully there is a solution. I have an LSI Megaraid 8x with four drives in a raid 5 configuration, in windows I was getting upto 60MB/s transfer rates but in FBSD I am getting upto 9MB/s. I followed the instructions in the handbook for tuning disks and I have set dma on. Being new to unix, I have no idea what to try or get system information too continue troubleshooting. If anyone could point me in the right direction or to appropriate documentation it would be much appreciated. Steve... -- Folding@home http://folding.stanford.edu/
