Net::HTTP should set TCP_NODELAY for requests with body
Setting TCP_NODELAY to disable Nagle's algorithm speeds up successive writes which
we use when sending HTTP PUT/POST requests with body.
The user-level solution is to avoid write-write-read sequences on sockets. write-read-write-read is fine. write-write-write is fine. But write-write-read is a killer. So, if you can, buffer up your little writes to TCP and send them all at once. Using the standard UNIX I/O package and flushing write before each read usually works.
We currently hit the killer write-write-read case when sending requests
with body using Net::HTTP
net-http-persistent does this by default (for all connections), even.
I usually use net-http-persistent, but sometimes it's easier to use
Net::HTTP on a new (bare) system and I've been bitten by this :x
