bshashikant commented on issue #578: HDDS-3053. Decrease the number of the chunk writer threads URL: https://github.com/apache/hadoop-ozone/pull/578#issuecomment-607157966 > > I feel with more no of disks per datanode for write, we may need more threads depending upon the load. > > I agree, with 1 hard disk I would use 3-4 threads. I proposed to use 10 which seems to be fine with ~5 disks and seems to be a good, balanced default. > > Should we use 20 instead of 10? Is there any reason to have exactly 60? There is no logic to use exactly 60. I am ok to make to 20 for now. We need to test with multiple disks and varying load to see how it really impacts the performance. We can even decide to make it a factor of number of data disks available per datanode but this can be done in follow up jira.
