[lwip-users] Sending too slow.

[Mateusz Plocinski]

Hi,
I'm currently working on building audioserver based on AT91SAM7X256 
microcontroller and freertos+lwip stack.
I'm new to lwIP and I encountered one problem while sending packets. When I 
send a frame (for example 32 KB), lwip sends it as 1.5KB packets and thats 
normal for TCPIP. But every packet it waits for acknowledgement from client 
(PC, WinXP). 
And PC sends it after 200ms!
I have to send about 100KB per second or more and waiting for ack 200ms is not 
possible. As far as I know, I have a right to send the whole window size 
(windows XP sends 65KB window requests) without waiting for ack.
My question: is it possible to make lwIP stack send packets faster without 
waiting for ack every single packet?

We, at our company have written a stack for AVR atmega128 which is able to send 
about 16mbits/s without problem (ack's come every few packets but Windows sends 
them much faster than every 200ms when it gets more data). But this stack is 
buggy and I would like to use lwIP on ARM7)
Can you tell me if fast sending is possible under lwIP or if this is only 
developed for slow, every-packet-acked connection?
Please help ;]
