There is also a rpc command to turn tracinf on/off, but it doesn't affect the trace_mode=1. Again, for the next major release we should revise and make those options work for all variants: mirroring or save to db, with control via modparams and rpc...

I looked at the code and looks like callbacks are not unregistered/registered again when tracing is turned off/on by rpc command. Doesn't that affect performance negatively?

I think it is like this with the tm callbacks since the very first version of the module. So it is nothing new in terms of performances comparing with older kamailio versions. Now, there could be further optimizations, if someone wants to squeeze more, but given that there is a sql insert anyhow, probably the overall gain is insignificant.
