Hello, 

I'm running a Dual Opteron 244 on a Tyan S2882, Intel SRCS16 Raid Controller
with 5x200GB WD200 7.2KRPM HDD's RAID5. 
The I/O performance is EXTREMELY slow, and sometime system is simply
inaccessable taking a minute to exit from writting a file! 
When I changed to Raid0 i/o increased noticebly. I tried using Windows 2000 on
the system and i/o performance was way better than under FreeBSD. Is their a
current problem with the MegaRaid driver? 

Thanks
