I think I tried everything possible... sometimes the network also freeze using other tools, but with PFTP it is
easy reproducible because using PFTP and VIA device I got a transfer rate from about 7.000.000 cps (about 7MB). This is
fine, this is fast!

I tested also some different PCI-Cards with RealTek 8139C & 8139D. Sometimes setting up the cards using the
Wizard, the PEG-II freeze totally. Later I am able to configure the network, but I only get 8.000 cps transfer rate.
But my switch is showing a 100MBit connection...
Yesterday a friend visited me and brought a 3Com 3C905B-TX network card. This card was working with
400.000 cps transfer rate (about 400kb).
Using Debian Linux 6.0.5 on the same hardware in the same network every card is working fine!
A guy from the MOS team told me that it listen like a DMA bug on the PEG-II?!?! Only a network without DMA will
work fine?
I just can say that my PEG-II is from the last production run with the last firmware, maybe they changed something?
What I can try is using AmiTradeCenter (using this only on 68k), AmiFTP is not usable because I have to transfer folders and AmiFTP has a big
bug that transfer rate will be very slow if you try to transfer folder.
