Hi, I use btrfs on most of my volumes on my laptop, and I've always felt booting was very slow, but definitely sure is slow, is starting up Google Chrome: encrypted ext4: ~20s btrfs: ~2:11s I have tried different things to find out exactly what is the issue, but haven't quite found it yet. Here's some stuff I got from latencytop, not sure if would be helpful: 4969.1ms sys_mmap_pgoff syscall_call (chrome) 1139.9ms sync_page sync_page_killable __lock_page_killable generic_file_aio_read do_sync_read vfs_read sys_read sysenter_do_call (chrome) 431.9ms sync_page wait_on_page_bit read_extent_buffer_pages btree_read_extent_buffer_pages read_tree_block read_block_for_search btrfs_search_slot lookup_inline_extent_backref __btrfs_free_extent run_clustered_refs btrfs_run_delayed_refs btrfs_commit_transaction (btrfs) Cheers. -- Felipe Contreras -- 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
