This read-write object enables or disables Nagle's algorithm for TCP connections on the device, which batches small outgoing packets to reduce network overhead. Admins disable it for latency-sensitive applications, such as interactive or real-time traffic, where waiting to batch small packets adds unwanted delay, and leave it enabled otherwise to reduce the number of small packets on the wire. For example, setting usrTcpNagleStatus to disable(0) on a device running a real-time control application prevents small command packets from being delayed while Nagle's algorithm waits to batch them.
