We've solved the problem increasing net.inet.ip.ifq.maxlen from the default of our version (50) to the default of the more recent versions (250). Does it make sens to you? How far do you think we can go with that value considering that we've 3 physical interfaces (int 100mbit, ext 100mbit and pfsync 10mbit) and that the servers have only 512Mb of RAM? Something like "Henning's rule" with 256*3 (number of physical interfaces) would be a good and safe choice with our hardware (of course we're planning an upgrade of both servers and openbsd version)? Thanks for your help Alessandro
