If I send flood pings to the other host with big packets (say 2000 bytes) it works, but one packet out of 4 or 5 takes a huge time to round-trip (about 1000ms), whereas the rest of the packets have a reasonable 0.2 ms average... I fear this may lead to unacceptable performance for real-time protocols (ie voip) in a production environment. Do you think the problem is localized in the "re" driver? If so I could just change the network interface and be done with that. (In production I can use bge cards). Thanks again.
