Subject [jira] [Commented] (HTTPCORE-368) Smarter use of buffers in SSLIOSession
Date Sat, 14 Dec 2013 10:09:07 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13848306#comment-13848306

Oleg Kalnichevski commented on HTTPCORE-368:
--------------------------------------------

Let me start off by questioning the wisdom of keeping 30k+ concurrent outgoing connections
that I presume are mostly idle, hence the problem with the buffers allocated by those connections.


Anyway this is what I see as a possible solution to the problem: introduce a strategy interface
injectable at the construction time of SSLIOSession and provide several implementations of
it: one basic based on immutable buffers and another one being being capable of deallocation
of buffers that appear unused. This would also open a possibility of creating a more sophisticated
strategy based on buffer pools.

> We're using the async client to load test our comet infrastructure. We're frequently
running in to OutOfMemoryErrors due to the ByteBuffers allocated in SSLIOSession.
> The following is a quick-and-dirty patch to SSLIOSession that removes the buffers when
they aren't needed. Could we get this (or something similar to this) added in to httpcore-nio?
