Thanks Kieran, i attach the files that you want. The error_LOG.rar is a capture of wireshark. This file is sending a big packet at the end. You can see the size of the packets browsing by the network. My application send packets to PC application, and this wait about 25 second to receive the full message (27Mbytes). My application need 87 second to send only 500Kbytes.
My aim is improve the speed a lot of. I hope to have enoght memory, because i have moved the dinamic memory to external memory, and i have reserved 2Mbytes for this purpose. I hope you can help me, and tell me the typical paramet tha i can modify of lwipopt.h thanks in advance Regards Oscar On Wed, Apr 7, 2010 at 6:02 PM, Kieran Mansley <[email protected]> wrote: > > On 7 Apr 2010, at 07:15, Oscar F wrote: > > > Hello everybody, i´m using lwip in AVR32 in EVK1100. > > > > I´m sending a big packet ( 15 Mbytes) , > > Your packets will be much smaller than that: your write of 15 Mbytes gets > split up into lots of smaller packets that the network can handle > efficiently (as you saw in wireshark). > > > and the time to finish the process is very high!!.
