I'm running a micro EC2 instance, and i've been seeing ... quite a lot of I/O usage (14+ million iops... for a webserver with barely 40 hits a day, plus spiders activity).
After playing with
iotop, i found that Apache is writing somewhere around 6.3 megabytes, if you hit it with a browser, after a couple minutes of inactivity.
It's not Swap Memory usage.
Do you have any idea about what might be causing this?
NOTE:: I used,
iotop -a -P to run this tests.
