Duong reassigned HDDS-7167:
---------------------------
Assignee: Duong
> Set the right default number of reader threads for Hadoop-RPC
> -------------------------------------------------------------
>
> Key: HDDS-7167
> URL: https://issues.apache.org/jira/browse/HDDS-7167
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM, SCM
> Reporter: Duong
> Assignee: Duong
> Priority: Major
>
> Hadoop-RPC decouples the reading of RPC requests (readers) from connections
> and the executing RPC requests (handlers) by an in-memory blocking queue.
> By default, there're 100 handler threads but only 1 reader thread, and this
> can easily be a bottleneck.
> We did a raw RPC benchmark in OM and verified that the pure RPC performance
> can be improved by more than 3X just by increasing the number of readers to
> 10.
> We should introduce a new config for the number of RPC readers in OM and SCM
> and define the right default value.
