Should I enable "tcp_tw_reuse" on my server?
Please note that this setting affects the networking configuration of the server. We do not recommend making any changes to this setting unless you have been specifically instructed to by a System or Networking Administrator.
The configuration tcp_tw_reuse allows reusing a client port immediately after the connection has been closed, even if the connection is still in TIME_WAIT state. The default configuration of this setting is normally preferred.
