[Gluster-users] Lots of connections on clients - appropriate values for various thread parameters
Hi Alberto, wow, good hint! We switched from old servers with version 4.1.6 to new servers (fresh install) with version 5.3 on february 5th. I saw that there was more network traffic on server side, but didn't watch it on client side - the traffic went up significantly on both sides, from about 20-40 MBit/s up to 200 MBit/s, on server side from about 20-40 MBit/s up to 500 MBit/s. Here's a screenshot of the munin graphs: network traffic on high iowait client: https://abload.de/img/client-eth1-traffic76j4i.jpg network traffic on old servers: https://abload.de/img/oldservers-eth1nejzt.jpg network traffic on new servers: https://abload.de/img/newservers-eth17ojkf.jpg Don't know if that's related to our iowait problem, maybe only a correlation. But we see the same high network traffic with v5.3. Thx, Hubert Am Mo., 4.
