A bit more information. On the slow system: # hdparm -Tt /dev/sdb /dev/sdb: Timing cached reads: 27784 MB in 1.99 seconds = 13934.26 MB/sec Timing buffered disk reads: 468 MB in 3.01 seconds = 155.63 MB/sec # hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 27776 MB in 1.99 seconds = 13930.08 MB/sec Timing buffered disk reads: 584 MB in 3.00 seconds = 194.66 MB/sec On a system acting as expected: # hdparm -Tt /dev/sdb /dev/sdb: Timing cached reads: 6852 MB in 2.00 seconds = 3427.26 MB/sec Timing buffered disk reads: 312 MB in 3.01 seconds = 103.56 MB/sec So at this level they seem to be okay. Not sure what this tells us. -- Yours sincerely, Roger Oberholtzer Ramböll RST / Systems Office: Int +46 10-615 60 20 Mobile: Int +46 70-815 1696 roger.oberholtzer@ramboll.se ________________________________________ Ramböll Sverige AB Krukmakargatan 21 P.O.
