Hi everyone, My programs are hungry for IO. When I inspect the server, the glusterfs process only use <300% CPU, and glusterfsd <200%. The Ethernet is pretty idle (<5% load) and bricks are at ease too (read+write <30MB/s). I already increased io-thread-count to 32 and event-threads to 8. What other measurement should I take?
