I will try to give you as many feedback as possible. :-)

I finally have a more or less working setup. At least there is no crash whatsoever, and the PS domain is working, the UE can attach, activate PDP, transfer data to some extent.

For example when i tried to ping the TUN interface, I got 2500-2600ms latency.

That's normal in the default case, since the MS will have to issue a RACH to get an uplink TBF for the response. You can allow to keep the PACCH open for a longer time by configuring

pcu dl-tbf-idle-time 2000

This keeps the DL TBF open for the time given (in ms) by periodically sending LLC dummy commands.
