Now i am in front of my PC. I already use the cfq scheduler and have low latency desktop enabled. I looked at the output of hdparm -I /dev/sda and all seems to be ok by default. > And check you have HZ set to 1000. > > $ grep HZ /usr/src/linux/.config > # CONFIG_HZ_100 is not set > # CONFIG_HZ_250 is not set > CONFIG_HZ_1000=y > CONFIG_HZ=1000 Thanks i will check if this helps, i have just set 250 HZ for timer frequency. > Could your problem be similar to this: > > http://marc.theaimsgroup.com/?l=gentoo-user&m=114252338111258&w=2 > > > Tom Maybe, today the gentoo-sources-2.6.19-r5 become stable so i will try the new kernel. I am also waiting for kernel 2.6.20 as it has a setting for the core 2 duo in processor settings. Maybe i try the testing version of it. Also the new gcc compilers will support the core 2 duo directly, but i think it will take some time till 4.2 or even 4.3 will become stable. I show up here again and tell you if something improves the performance of my system. Regards Daniel -- gentoo-user@gentoo.org mailing list
