Release Note:

Hide
This patch increases the default scanner caching to 100.
It also enables tcpNoDelay by default (i.e. disabled Nagle's algorithm).

This will generally lead to better performance, but in some situation may lead to different network patterns and increase memory consumption on both the client and the server.
