> Potential speedup. Mladen is thinking about porting java.net to APR, then we would just need to prepend the LD_LIBRARY_PATH with apx.so
> Email from Mladen:
> Couple of extra notes...
> With additional transport protocols (NT pipes and unix domain sockets)
> beside standard TCP you can also use additional interface that
> can take a NIO direct ByteBuffers.
> Only that gives the 5-10% overall speed improvement over
> standard implementation, because it lowers the JNI function
> calls compared with standard java.net
> Also since the JGroups is mostly packet based, having a poller
> for input events will give you the chance to lower the worker
> thread count, without the need to change the entire processing
> logic to NIO bullshit. For example APR/AJP protocol in JBossWeb
> can easily handle 10000 connections with only 100 threads with
> negligible performance impact.
> When you guys are ready to dig into APR, I'll help you with
> the implementation and API usage.
