Pe1950 Hd test speed

[Claudio De Luca]

Hi,

i am testing two Pe 1950 with 2x 143 Gb Sas hard disk and Perc 5 controller, why i get a so slow test? i need to enable something on the controller?

root at zeus ~]# hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   9720 MB in  2.00 seconds = 4867.20 MB/sec
 Timing buffered disk reads:  208 MB in  3.59 seconds =  57.99 MB/sec

root at avalos [~]# hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   1340 MB in  2.06 seconds = 650.27 MB/sec
 Timing buffered disk reads:  142 MB in  3.48 seconds =  40.76 MB/sec

my vps on Pe2950 is more fast :(

-bash-3.1# hdparm -Tt /dev/sda1

/dev/sda1:
 Timing cached reads:   12876 MB in  2.00 seconds = 6445.96 MB/sec
 Timing buffered disk reads:  428 MB in  3.01 seconds = 142.30 MB/sec
-bash-3.1# hdparm -Tt /dev/sda1



Thanks
Claudio
