if it does parallel IO on multiple files, then the scheduler will make a difference. since this is a setup with only 2 servers and 2 copies of files are there, unify is not really needed. I need to check with krishna what is the current status of AFR read load balancing (which will play the main role here). so using the 'option read-subvolume local-posix-volume' (overrding read scheduling) will make server AFR read performance equal to client side AFR since scheduling reads on server side will make reads have 2 hops. avati 2008/1/8, Sascha Ottolski <ottolski@xxxxxx>: > > Am Dienstag 08 Januar 2008 10:59:18 schrieb Anand Avati: > > > > was it just one file being read/written? if not please use rr (a > more > > > > deterministic scheduler) and share the numbers please. > > > > > > I did only the bonnie tests, posting I put the link in wasn't by me. > > > > my reply was with reference to the bonnie results alone, and not from > the > > link. > > > > avati > > well, then it's not just one file, bonnie does a whole bunch of tests on > several files. unfortunately I don't know all the details... > > Cheers, Sascha > > > -- If I traveled to the end of the rainbow As Dame Fortune did intend, Murphy would be there to tell me The pot's at the other end.
