Hello,

Hier is a problem that we have with a FreeBSD 4.3-REALEASE and I 
think that it is more a bug that a problem.

We wanted to run a system with installed 3 Promise FastTrack ATA/100 
controllers with 10 70GB IDE Hard Drives. Internal IDE controllers 
were turned off and a SCSI Hard Drive was used as booting device.

On 4.2-RELEASE using vinom we managed to run RAID-10 (or what vinom 
calles RAID-10) and we had perfomance of 30 MB/sec sequential writing 
to this ata harddrives. But the 4.2 system was unstable and crushed 3 
times in 2 days during the havy load.
On 4.3 system it seems to be more stable (but we did run it only 
several hours) and the performance was horrible:
about 8 MB/sec for writing.
