Plain profiling (perf record/report) shows approximately what I'd expect if things were working properly - lots of time in lots of routines, lookup fops especially noticeable but nothing dominant. At this point I think it's less about raw execution time than about what executes in which order. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
