Re: [Gluster-users] slow write perf for disperse volume

I've done some more testing with tc and introduced latency on one of my testservers. With 9ms latency artificially introduced using tc ( sudo tc qdisc add dev bond0 root netem delay 9ms ) to a testserver in the same DC as the disperse volume servers I get more or less the same throughput as I do

Re: [Gluster-users] slow write perf for disperse volume

We were able to saturate hardware with EC as well. Could you check 'top' in threaded mode to see if fuse thread is saturated when you run dd? On Mon, Apr 24, 2017 at 3:27 PM, Ingard Mevåg wrote: > Hi > I've been playing with disperse volumes the past week, and so far i can >

[Gluster-users] slow write perf for disperse volume

Hi I've been playing with disperse volumes the past week, and so far i can not get more than 12MB/s when i do a write test. I've tried a distributed volume on the same bricks and gotten close to gigabit speeds. iperf confirms gigabit speeds to all three servers in the storage pool. The three
