Hello, with drbd-8.0.14 or 8.0.16 on the same machines: My tests are "copy big files on the replicated device". This takes for a file 8 seconds. instead of 0.2 seconds without drbd if kernel version is 2.6.27 or 28 or 29. but with kernel 2.6.20 there is no performance problem: it takes sensibly the same time to copy this file if drbd is running or not. I alway use the same drbd.conf for these tests. have you some ideas about why drbd is so slow with kernels 2.6.27 to 2.6.29? regards, Lise Didillon -- Lise DIDILLON Ingénieur d'études, Ligne Produit UseIT lise.didillon at prologue.fr <mailto:lise.didillon at prologue.fr> ------------------------------------------------------------------------ logo prologue <http://www.prologue.fr> ZA de Courtaboeuf 12 Avenue des Tropiques BP 73 - 91 943 Les Ulis Cedex Tél : +33 1 69 29 39 39 Fax : +33 1 69 29 90 43 -------------- next part -------------- An HTML attachment was scrubbed...
