hi everybody i recently switched from a 3.1 kernel to 3.2rc4 from fedora rawhide. since i switched i am having serious performance isues, mainly due to my limmited cpu (1.6Ghz attom single core) when i boot in 3.1 my bootup is mainly I/O limited (according to bootchart) when i boot in 3.2 my bootup is compleetly CPU limited and takes a lot more time also file actions (like tar -xf linux-3.1.tar takes) are a cpu hogg, according to top most of the cpu usage is in kernel space, and i see different btrfs threads at the top time tar -xf linux-3.1.tar.bz2 real 11m10.037s user 1m26.861s sys 5m26.738s cpu usage 8%user, 82%sys, flush-btrfs-5 50% tar 45% btrfs-endio-write 20% btrfs-transaction 15% it would be nice if somebody could look into this, and hopefully get it fixed in 3.2 final (i am not a kernel or btrfs guru, so i don't know where to start looking for the problem) greetings Simon Peeters -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
