In the hope of improving systems speed I had also removed all snapshots then defragged the FSes - the snapshots have been recreated since, as I use the excellent SuSE "Snapper" tool. But well, all 4 machines are still slow like hell. All of them are used for quite basic daily tasks - web browsing, email, typical LibreOffice tasks, nothing very mysterious there, no specific heavy DB work. All machines have 64-bits Linuxes (either Ubuntu 12.10 or 13.04ß), with decent amounts of RAM - 2 GB to 4 GB - and disks filled less than 75% With such a setup, I would expect any decent filesystem to deliver excellent performance. Still, all of my machines are slow like hell and I'm most of the time in mode « Working my patience while waiting for the HD LED to go off ». I haven't noticed any real-life noticeable improvement upgrading the kernels from 3.5.x to 3.8.x So I'm wondering... -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook.
