Symptoms

Connections are intermittently slow when using TCP and the Listener.

Timing shows:

a) simply time test -->


This is occurring at a Network Read (nttrd).
However, not ALL Network Reads, but scattered across nttrd functions (some are normal, some are 10x slower).
Because there is such a variance in returning network read data, queries that should take a few seconds are taking 10x to 100x longer.
