In my observations with ib, I've noticed in that the vfs performance can be quite lacking. can you try unmounting the vfs and rerunning the test to make sure you're using libpvfs2 and not the vfs? ~Kyle _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
