Hi i am back again!
Unfortunately my problem is still bugging me!
I will give short overview what i have tried so far.
1. Trying different I/O Scheduler ( cfq anticipatory and deadline)
2. Enabling Low latency kernel and Preemptible kernel
3. Setting 1000 HZ for timer frequency
4. Tried the new kernel 2.6.19-gentoo-r6 and even the testing version
2.6.20-gentoo with core 2 enabled in processor type
Nothing seems to help.
Hdparm also shows me that my disk has
IO_support = 0 (16-bit) set instead of
IO_support = 1 (32-bit)
I can't set it to 32 bit as hdparm can only display settings for sata
disks but not alter it.
I tried sdparm and blktool but there seems to be no option for it.
As i am using Xfce i installed the diskperf-plugin which monitors disk
I/O. The monitoring is divided in disk-read and disk-write.
I recognized that every time when reading stops writing starts. So is
this staggering of writing to disk normal as the programs have to read
data they want to write to disk? On my previous machine i didn't
recognize such a behaviour.
