I reported this in May 2006. Found in nsd-3.0.6/doc/TODO:
- From Aaron Hopkins: write tcp length and tcp data in one write operation,
instead of multiple calls to write. Avoids Nagle algo delay in this case.
preallocate 2 bytes in front of buffer to put them into.
There are a few other performance-related things I reported at the same time
still in the TODO that you might be interested in.
