[lwip-users] disconnect - connect delay

[brak brak2]

Hi,

I'm developing a HTTP server using the lwIP with only one connection 
available at the time (I set MEMP_NUM_TCP_PCB to 1) on the Stellaris 
LM3S6965. The program works fine, but I have very long delays between 
closing one connection and establishing a second one, but only when the second 
one is waiting for connection before first one closes.

The problem appears only 
then I try to make a second connection when the first one is still 
active. The second connection is waiting for ACK - just as I want it - 
until first connection closes. But when the first connection ends, the 
second one is still waiting for more or less 2 - 3 seconds. After this 2
 - 3 seconds the second connection is establishing.

How to handle this correctly? How to make a second connection establish as soom as the first one closes?

Now when I downloading website from the lwIP HTTP server waitting time for establishing connection is about 3 seconds for each website element.

Log from firebug shows that waiting time is much longer then downloading time:

I found this: 
http://old.nabble.com/Slow-release-time-of-closed-TCP-PCBs-td24077502.html
but
 I changed TCP_MSL to 600U, TCP_KEEPINTVL_DEFAULT o 7500UL, 
TCP_FIN_WAIT_TIMEOUT to 200 and TCP_SYN_RCVD_TIMEOUT to 200 and it 
doesn't change anything! 



PS
I use callback functions conn_established and conn_closed to measure connection and disconnection time.

Best regards
Tomasz
