I do not know if the 2.4 driver has the same problem. well, i don't have a raid or mirror container configured. the driver from 2.6.0-test9 (vanilla) runns nicely in fact, but is really, really slow, my UDMA IDE machine is quite fast compared to the MPT. (FYI: colleagues having the same machine running win2003 also tell me the disks are relatively slow) further, i kindly heard from Dan Creswell that several people experience performance problems with this controller and that LSI is also aware of that and eager to fix this. / karl
