Re: [lwip-users] Acknowledgment frequency and throughput degradation

Can't tell if this is the client or the server, but either way, make sure your Windows system is configured to disable Ack Delay,  You can Google TCPAckFrequency and TCPNoDelay, or see http://us.battle.net/d3/en/forum/topic/5578595314 for instructions.  You will have to reboot your Windows box after adding these.

 

You can find the correct Interface by looking for the correct IP address in the GUID entry.

Subject: [lwip-users] Acknowledgment frequency and throughput degradation

I am running LwIP on BF527 as server with windows 8 as client.

TCP_MSS 1460

and adjusted the send and receive buffer size accordingly.

I am  seeing an ACK every second packet, regardless of the windows size I am setting.

That is affecting the throughput  I am getting.

I am attaching the lwipopts.h and pcap files.

I would appreciate any help

Thanks.
