I didnīt yet provide such a test case. At the moment I can only reproduce this kworker thread using a CPU for minutes case with my /home filesystem. A mininmal test case for me would be to be able to reproduce it with a fresh BTRFS filesystem. But yet with my testcase with the fresh BTRFS I get 4800 instead of 270 IOPS. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
