Dear devs, My filesystem is super-sluggish since about a week, and perf top tells me that find_next_bit(), find_next_zero_bit() is eating my netbook's CPU.
The kernel is 3.3-rc3+188 (g3ec1e88) and I don't use this laptop a lot, so I'm ready to cooperate. In the btrfs-transaction thread, in descending order of CPU usage: find_next_zero_bit, find_next_bit, rb_next, setup_cluster_bitmap, setup_cluster_no_bitmap, tree_search_offset. I'm on #btrfs (Zougloub) Regards, -- cJ -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
