You have a few lates, but not too many. This can be solved with thread affinities and/or use of DPDK. Please check KPI on the RU as well and check if it's emitting a signal. |

I checked the kpi.sh and i have a few RX_late (between 34 and 37). I tried various configs for the CPU pinning without much success. I verified with Network Signal Guru and I can't see the SIB. Which of the pinning parameters typically help in those cases? |
Hello!
Issue Description
I managed to run srsRAN with RAN550 on a beefy xeon server fine. I now want to run it on a smaller PC but I keep getting timing issues in the flavor of (see the attached logs):
The UE also does not attach in this setup but it did on the xeon server
Setup Details
Expected Behavior
The UE should attach
Actual Behaviour
The UE doesnt attach but the RU receives all the packets on time. However the DU does not seem to receive anything
Steps to reproduce the problem
Here is the config file I am using (same as the xeon server, baring the big server uses a remote core while it is local in that setup)
Additional Information
i used the srs_performance script
