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 ½ 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.
