Does it mean a single thread at the client or a sigle thread per core?? My problem is with the case=netdisk that gives me low performance for single thread (the dd case). (as well as with the ost_survey case). Is the case=netdisk a valid test ?? I am trying to isolate the problem and the case=netdisk alows me to avoid accessing the mds (right?) Any Idea?? ----------------------oo--o(:-:)o--oo---------------- Lior Amar, Ph.D. Cluster Logic Ltd --> The Art of HPC www.clusterlogic.net ----------------------------------------------------------
