Hi,
We use ignite as a redis server.
The use case is
a. Write timeout is 15ms on the client side.
b. 2 server nodes. each is an EC2 r4.4xlarge instance.
c. Write req/s is about 120,000. In another word, 60,000 for each node.
The problem is that timeout happens frequently, several ones per second.
A lower write req/s results less timeout. I guest we have bottleneck somewhere.

$ tail -f /opt/apache-ignite-fabric-2.5.0-bin/work/log/ignite-ee4f25ed.0.log
| grep pool
^-- Public thread pool [active=0, idle=0, qSize=0]
^-- System thread pool [active=0, idle=16, qSize=0]
==========
system thread pool seems not busy at all.

$ tail -f /opt/apache-ignite-fabric-2.5.0-bin/work/log/ignite-ee4f25ed.0.log
| grep "CPU "
^-- CPU [cur=14.77%, avg=6.21%, GC=0%]
^-- CPU [cur=13.43%, avg=6.23%, GC=0%]
==========
CPU is not busy, either.
We expected milli second level performance and we have too many timeout now.
Any idea for optimizing the performance?
Thanks.
