hello
i have a centos server
2 X dual core 1.6 ghz
with 4 gb ram
with around 4200 email boxes
i was facing problems of high load during office hours -- top command used
display load ranging from 5 to 35. I log server load every minute.
i increased ram from 4 gb to 8 gb and processor from 1.6 ghz to 2 ghz but
However it did not make any significant change in the load.
Then i upgraded from the 250 gb sata drive to a 1 TB sata drive
there was a huge change in the load -- the load came down dramatically it
is now between 1 - 2.5 even during peak working hours
what could be reasoning for this ?
is this related to disk i/o ?
I think you answered your own question there. The load dropped after you
changed the drive, so I think it would be safe to say that your drive
was introducing latency.
I also have some videos (http://video.qmailtoaster.com) that show some
tips on how to increase throughput on your system.
