Hi, I've got four HDDs and added them into a RAID-5 array, which basically works just fine. However the performance sucks quite hard. I get only about 70 MB/s when it comes down to reading and writing speeds of about 35 MB/s. The hardware itself is quite decent: Intel Xeon E31260L, 8 GB RAM and four Samsung HD204UI's. With the same setup and a Ubuntu live environment I get about 270 MB/s reading speed and 130 MB/s writing speed. Therefore there must be a fundamental difference. I've compared various values from sysctl between both environments and set them accordingly, but to no availability. Anyone else experiencing the same issues and/or can you point me in the right direction? At least I would like to saturate my Gigabit Ethernet connection. Best regards, Karol Babioch
