What algorithm (PCU) would you prefer if the goal is to maximize the single UE throughput?
UL is one PDCH in general with either algorithm.
For DL: Algo B (multislot) if you have >1 PDCH. In branch jerlbeck/master (which will be merged to master soon) you can also use 'alloc-algorithm dynamic' which will provide a higher DL throughput if there are only a few connections and will move over to algo A on higher usage.

Jacob

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.
