>From my research on the FreeBSD platform you can't toggle TCP_NOPUSH to
indiciate flushing of buffers like you can with TCP_CORK on other
platforms.
When I compile with the nopush options I get very long delays (>2sec) for
some queries. Commenting them out the delays go away.
My vote is for yanking NOPUSH for FreeBSD... sound reasonable?
Besides nagle should absorb most of the performance hit associated with
short writes?
Have Fun!
