I have just tried the tcp_echo test on my ARM7TDMI (Samsung S3C4510A) system.
With the old tcp stack I get the following results:

Start TCP test - SOURCE mode to 192.168.1.75
SOURCE complete - 1024 bufs of 8192 bytes in 138.50 seconds - 59.15 KB/S - 
0.4845 Mbit/S (M = 10^6)

Start TCP test - SINK mode to 192.168.1.75
Using 1024 buffers of 8192 bytes each
SINK complete - 1024 bufs of 8192 bytes in 138.87 seconds - 58.99 KB/S - 
0.4832 Mbit/S (M = 10^6)

Is this a normal result?

The test with the new tcp stack is running since more the 15 minutes without a 
result. I can see that there is sometimes traffic on the network, but alway 
with long delays.

Does anybody know what the problem could be?
