|Subject:||[lwip-users] Minimizing TCP send delay with RAW api and multi-threading.|
|Date:||Thu, 11 Nov 2010 15:49:59 -0500|
Are there any safe “tricks” to get TCP data sent faster from a non tcpip_thread? Since the RAW api is not safe for concurrent access, it seems the delay will always be a factor of the tcp_tmr intervals (fast&slow). With that in mind, the only way to reduce the delay is to adjust these tmr values to get the TCP_EVENT_POLL to happen more frequently.
What are the ramifications of adjusting the coarse/fine timer values? Is this a common practice to reduce asynchronous transmission delay? Has anyone had experience “tweaking” these values to minimize send delay?
As always, thanks for your time.
