-----------------------------------
[~andywu], how many clients are there? Could you try benchmarking the server
(bypass the RaftClient, call the server methods directly)?
Apache Ozone has over 100k IOPS; see

> Improve the read latency of RaftClient

> Project: Ratis
> Issue Type: Improvement
> Components: client
> Reporter: Andy Wu
> Priority: Major

> Hey Folks,
> We are using ratis library to perform around ~2K/s read operations. Here is
> the API we are using:
> {code:java}
> RaftClient#sendReadOnlyAsync ==> it is OrderedAsync{code}
> I understand the above API is ordered, it will be filed sequentially. The
> read latency is keeping going up for each cid:
> e.g.
> duration: 15 ms, cid=2
> duration: 20 ms, cid=3
> …..
> duration: 100 ms, cid=100
> For the read operations, the order is not important to us. How do we improve
> the latency while keeping the throughput high? I tried *UnorderedAsync,* it
> has similar behaviors. Anything I missed?
