Re: [lwip-users] lwIP RAW - Low throughput during first few seconds

[Nenad Pekez]

It turns out I made conclusion too soon...

The 5 seconds problem still exists but is quite rare (1 in 20 iperf 
client executions). Also, new problem is introduced - sometimes I also 
get connection timeout. I forgot to mention that Ethernet (emacps) 
Xilinx drivers were also updated to latest version (when we updated lwip 
to 2.0.2), and it is noticed that in combination lwip2.0.2. with older 
emacps version this connection fails are much often (it is not possible 
to make 2 consecutive connections). It seems this is a problem with 
Xilinx drivers, so it doesn't concern the lwip 2.0.2.  I will try to see 
what is happening inside those drivers and eventually write to Xilinx 
support.

Thank you anyways,
Nenad
