Hello, We have the following network card em0: <Intel(R) PRO/1000 Network Connection, Version - 1.7.35> being controlled by 5.4-STABLE/SMP. The problem that we face lies in low data transfer speed from server to network. The card is connected to 100Mbps port of the switch (setting speed/duplex or autoselect option does not have any influence on the results). If there is a file downloaded via FTP from the server the speed is hardly higher than 4MBps. However, there is a flaw: if we launch trafshow -npi em0 outgoing transfer speed will immediately rise up to 12MBps, if we stop trafshow we get the low speed problem again: 4MBps. Please, help us locate the reason of such a low data transfer speed. -- APR-RIPE
