Hi Tim, Have you tried disabling the Nagle algorithm? I had a similar issue as I am only sending small packets of data. Once I had disabled the Nagle algorithm responses to the client were much faster.

From: [email protected] [mailto:[email protected]] On Behalf Of Tim Lambrix Sent: 07 March 2011 16:02 To: [email protected] Subject: [lwip-users] Fast Response TCP Connection I am using a TCP server that must send out data to the single connected client pretty fast. However, I only see a TCP packet transmitted every 200 ms. How can I speed this up? Are there other settings in the lwipopts.h file that I should configure to make this application run without issues?
