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.

> Smarter use of buffers in SSLIOSession

> Key: HTTPCORE-368
> URL: https://issues.apache.org/jira/browse/HTTPCORE-368
> Project: HttpComponents HttpCore
> Issue Type: Improvement
> Components: HttpCore NIO
> Affects Versions: 4.3-beta2
> Reporter: offbynull
> Labels: patch
> Attachments: SSLIOSession.patch

>
> 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?
