Webserver with RAID-5 - performance problem
We have a new server which we want to use as a webserver. The following
hardware components are included:
- Intel XEON 3GHz
- 2GB RAM
- Intel SRCU42L RAID Controller SCSI
- 3 Fujitsu u320 SCSI discs in a RAID-5 array
We've installed Debian Sarge.
The problem is, that we've been running hdparm on the RAID device with
these result:
----
hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 138 MB in 3.04 seconds = 45.39 MB/sec
----
The result is not looking good.
At home I use a SATA HD, the hdparm result is about 60MB/sec.
I would be very thankful for any suggestion for solving these problems
