[Gluster-users] glusterfs + performance-tuning + infiniband + rdma
Hello, I tried some performance tuning options like performance.client-io-threads etc... & my throughput performance increased to more 50%. Since then I am trying to find what are the performance tuning parameter to increase the write throughput. The logic goes: If I get xxxx MBps using local SSD, then if I run the same test on GlusterFS(2x-distribute), do I get 2x the throughput or ? the time as localSSD. I know writes can't be near like localSSD. But I am using RDMA & I can feel there are some GlusterFS tunable to increase write perf, as I was able to increase write perf by 50%. Anyone, sharing some basic guidelines is appreciated. -- Deepak ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.

Anyone who have tuned glusterfs performance for read and write IO ? -- Deepak On Feb 20, 2017, at 9:24 AM, Deepak Naidu <dnaidu at nvidia.com<mailto:dnaidu at nvidia.com>> wrote: Hello, I tried some performance tuning options like performance.client-io-threads etc... & my throughput performance increased to more 50%.
