simpleran: various fixes, tx_power_offset, xlog disabled by default for 5G ORS services
This MR is a follow up to !1758 (merged) , which contained issues and was not deployed on client's ORS.
@kirr , I'm tagging you just to let you know this MR will disable xamari service by default on 5G ORS services for performance reasons (there are a bit more info in the corresponding commit). I am not 100% sure of the impact of xamari but we had a issue of high CPU load on a client's ORS running 5G TDD MIMO 2x2 40 MHz even after I disabled DRB polling, disabling xamari service allowed the CPU load to drop enough so that the ORS could run smoothly. This is supposed to be temporary until we find a solution, here are some courses of action for the future:
- Upgrade the computer: all future ORS are planned to have a more powerful computer we are currently testing, it should surely enable us to run xamari without along with TDD MIMO 2x2 50 MHz
- Optimize slapos node CPU load: this could surely help
- Optimize xamari: not sure if this is possible or needed
