Hello Arno, 1GB networks are very difficult to tune as many hardware behind the network cards can't handle such high speed, for example hard drives on "client" machines usually can't handle full 1Gb speed reception and will stay at average 80-100Mb only this making different bottlenecks on the machine that could go 100% CPU when it should not.
Also an other thing, if you force 10Mb or 100Mb on one side you may encouter some problem if other side is set to auto-negotiate as the other side will always try to re-negotiate to higher speed (and them produce a lot of garbage due to negotiation). regards.
