Hi all,
Rather later than I had hoped, it looks like we are in a position to tag
9.0.28 and 8.5.48. As usual, I'll run the unit tests on various
platforms and, assuming all is well, tag shortly afterwards.

According to the Javadoc, the Selector has various impls and is encapsulated
via a SelectorProvider. The chosen provider decides about which system api is
being used (poll, epoll, event ports, kqueue, ...).

With NIO2, when I set a really low send buffer (I tried as low as 32 bytes) it
does change what the read/write logs from TestNonBlockingAPI look like as
expected, but the "performance" does not go down
https://bz.apache.org/bugzilla/show_bug.cgi?id=63916
--- Comment #19 from Mark Thomas ---
Hmm. No change at all with a Executor. The cut-off for buffer size between good
and bad performance is still exactly 4537 bytes. That doesn't match with what I
thought was going on.

Hi,

Tomcat is calling write until 0 bytes are written before adding to the poller
so that isn't what is going on here.

By default on my Linux the socket send buffer size is 2304. For NIO to have the
same "performance" and behavior running the test [as seen with the debug logs]
as NIO2, the send buffer size needs to be
53 matches
