Kirill Gusakov updated IGNITE-20873:
------------------------------------
Description:
During the following workload:
- 1 node
- fsync disabled
- key-value put queries is executing one by one
We found out, that significant amout of time wasted
[here|https://github.com/gridgain/apache-ignite-3/blob/00e51e2b2e2e22ac48b64e9dfedacc0f03112543/modules/raft/src/main/java/org/apache/ignite/raft/jraft/rpc/impl/IgniteRpcServer.java#L190]
- up to 10us (the whole query time 80us). It looks strange, because during the
simple 1thread put test - there are no other tasks in executor queue.
This issue is reproducing during the YCSB one-threaded put test or with
SelectBenchmark.kvGet. Some more details can be found in attached doc.
