Hi,
I have been experiencing some odd behaviour (major slowdowns) in my laptop for some weeks now. After some investigation it turned out that hard disk performance was the reason. My buffered reads were way below the average when running hdparm -tT /dev/hda. However, this only occurred at some points in time. Since it was hard to reproduce I did not report the problem.
Yesterday I have finally been able to narrow down the cause of the problem. This slowdown occurs if my cd-rom drive is open or if there is no disk in it. Even though I don't understand how this is possible, the figures from hdparm -tT /dev/hda follow:
I'm sure this was discussed on the list (it could have been in fedora-test, though...) on the last week.
Please, search the archives.
