[Gluster-users] 3.10.5 vs 3.12.0 huge performance loss

[Serkan Çoban]

Hi,

Just do some ingestion tests to 40 node 16+4EC 19PB single volume.
100 clients are writing each has 5 threads total 500 threads.
With 3.10.5 each server has 800MB/s network traffic, cluster total is 32GB/s
With 3.12.0 each server has 200MB/s network traffic, cluster total is 8GB/s
I did not change any volume options in both configs.

Any thoughts?
