This variable helps you tune one element of low-level socket communication between a client and server. The setting of AGS_TCP_NODELAY determines whether the Nagle algorithm is used to affect the frequency of socket communication. The Nagle algorithm is a method by which the transmission of small socket packets is briefly delayed so several can be sent at the same time. Setting this variable to "false" causes the algorithm to be used.
The default value is "true", which results in immediate individual packet transmissions. The default value is probably adequate in most situations.
