----------------------------------------
Summary: I would like to know reason, I am observing significant
CPU utilization improvement after migrating to latest version, I need to
justify same to our stakeholders
Key: DIRMINA-1134
URL: https://issues.apache.org/jira/browse/DIRMINA-1134
Project: MINA
Issue Type: Wish
Reporter: kjhawierhjbasdf
Hello Team,
We are using Apache MINA(v2.0.21) for tcp tls server implementation. I have 2
queries.
1. CPU utilization query
We were using 2.0.9 before, and we saw there were few issues related to high
cpu utilization reported with our service. Then we recently migrated to 2.0.21
and we are seeing significant improvement in cpu utilization. Its using less
cpu without degrading performance.
Can you please confirm, If there are any fixes released in-between which can
cause such improvement. I have to provide justification to our stake-holders
about the improvement, they suspect that - It may not be the improvement, It
may be the code changes which is limiting CPU usage to single core.
2. Processor count query
Earlier, we were using default constructor for NioSocketAcceptor object, which
creates number of processors equal to number of cores.
But, In our case, we have few more services running on the machine, And I am
thinking to use NioSocketAcceptor object and pass the processor count with 1 or
2. I have verified this change, I did no see the performance degradation with
our service.
Do you see any problem with this? Anything else needs to be considered before
we go ahead with this change?
Thanks,
Rupesh Shah
