It is not my mistake, because I always do it the same way, new kernel, then music on. The problem is not present in rc7-git4. I could measure it in some way (timing ls -la in tht dir?) if somebody needs it. Regards, Piotr HosowiczYou tried mblk_io_submit mount-option for that partition?No, I do not use it, I do not even know what it is. My options are: /dev/sda2 on / type ext4 (rw,errors=remount-ro)Have a closer look at "ext4: Turn off multiple page-io submission by default"I tried to Google for mblk_io_submit but I didn't find anything helpful. Could you tell me how should I add this option in fstab and what will be its effect?As far as I understand that option regards writing, not reading. The symptoms I described occured while reading only.That's the only performance issue I am aware of in ext4 in recent time. Why don't you try it and present some numbers in transfer ratio (write, read)?Ok, I'll try to measure it in shell. Now I am building newest non-next kernel and the trial script is: #!/bin/bash uname -a mount cd /data/music time ls -d * cd - This is basically what mocp does when it enters my music directory, apart from displaying the results in ncurses based UI. Then I'll reboot with next kernel and run it again. Will it do?
Sorry for the desinformation, now I see that there must be some othe things that mocp does because when I measured it I see that my initial observaions were false. The script is attached, plain is the newest ordinary kernel 2.6.37-rc7-git5, _1 file is the first run, _2 is the second run. Similarily the next_ files, after mounting / with the option in question. They show no big difference between the kernels.
