Hi again Goffredo, Le 08/10/2012 13:38, Goffredo Baroncelli a écrit : > I fear that both the combination of autodefrag and the high number of > snapshot could be the root-cause of the the bad performance. I've removed, on one of my machines, all snapshots but three per subvol (keeping the oldests and newest), going from about 30 per subvol to 3, for the complete filesystem from 120+ to about a dozen.
Then I let btrfs-cleaner do its job After that the machine boots to GUI in a bit less than 2 minutes, where it was more than 4 minutes previously. The machine now seems much more reactive and swift. So it seems that the number or active snapshots (or is it the number of subvols whatsoever ??) dramatically impacts performance... Thanks for the suggestion. -- Swâmi Petaramesh <sw...@petaramesh.org> http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
