[Gluster-users] How to Speed UP heal process in Glusterfs 3.10.1
Normally I see 8-10MB/sec/brick heal speed with gluster 3.7.11. I tested parallel heal for disperse with version 3.9.0 and see that it increase the heal speed to 20-40MB/sec I tested with shd-max-threads 2,4,8 and saw that best performance achieved with 2 or 4 threads. you can try to start with 2 and test with 4 and 8 and compare the results?
