Hi, I'm been playing with the FreeBSD port of GlusterFS and it seems to be working ok. I do notice that the daemons use a lot of CPU, even when there is nothing to do (no volumes started, etc). When I ktrace the daemon, I see a small number of nanosleep() and select() syscalls and lots of poll() syscalls (close to 1000/sec). Looking at libglusterfs/src/event-poll.c, I find: ret = poll(ufds, size, 1); in a loop. The only thing the code seems to do when poll() times out is a call to event_dispatch_poll_resize(). So, is it necessary to call event_dispatch_poll_resize() 1000 times per second? Or is there a way to make event_dispatch_poll_resize() return quickly when there is nothing to do? I'm guessing that Linux uses the event-epoll stuff instead of event-poll, so it wouldn't exhibit this. Is that correct? Thanks for any information on this, rick ps: I am tempted to just crank the timeout of 1msec up to 10 or 20msec. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
