Hello Alexandre, ... AT> It's "normal" performance about me... AT> After i updraded to the kernel 2.6.x, and now this the new performance: AT> As u can see , the difference is so big, my raid 0 software on kernel AT> 2.6.x has a rate lesser than a single disk...??? ... AT> i made severals times the tests, and the results are the same... AT> The difference between my kernel 2.4.22 and 2.6.x is, that in 2.4.22 AT> the loading of "raid0.o jbd.o and ext3.o" are doing by the initRD and in AT> my 2.6.x the modules are built in the kernel (cause i don't success to AT> create an initRD which works..:( ) AT> What do you think a bout it ? AT> The kernel 2.6.x is bad for raid0 or i make an error in installation ? I can´t help you, because i don´t know something about that. But i´ve watched the same results on my Gentoo System The difference is: I had an "Softram" aka md-raid. Under my 2.4.22 Kernel Performance near then 80 MB/s under 2.6.x-beta11 und 30MB/s. Normaly one HDD takes about 42MB/s. After that i take a change and test the System with my PDC20276 (onboard). Nearly the same results. With 2.4.x Kernel-Driver incl. nearly 81-82MB/s and under 2.6.x less then 36 MB/s -- Greetings, Andreas mailto:andreas@xxxxxxxxxxxx
