Hi Oleg,
Thanks, Yes this does solve most part of the problem, may be we can make
it a configuration as well apart from the automatic tuning that you are
planing to do, so in case if the autodetection fails for enabling that
users can do it manually using the nhttp.properties file.
But, it still brings IOReactor down on high loads, where SUN JDK has no
issue at all in serving. I will dig more into the issue and share any
information if I could find the issue.
How exactly does that happen? Are you seeing any exceptions?
Oleg
Thanks,
Ruwan

Ruwan,
The IBM JRE compatibility mode needs to be activated using this
parameter:
http://hc.apache.org/httpcomponents-core/httpcore-nio/apidocs/org/apache/http/nio/params/NIOReactorPNames.html#INTEREST_OPS_QUEUEING
Per default HttpCore assumes the underlying JRE has a sane
implementation of
SelectionKey.
I will be out of contract as of next week and will have lots of
spare time on
my hands. I am planning to contribute a piece of code to Synapse
that turns on
interest op queueing depending on the JRE and as well as some other
minor
imrovements.
Cheers
Oleg
