[SR-Dev] what if ...

[Daniel-Constantin Mierla]

Hello,

what would be the drawback of having sip_msg being all the time in 
shared memory? Would pkg vs shm operations have relevant impact?

 From personal observations, most of the requests (over 95%) end in TM 
module (to absorb retransmission or to forward) where the sip_msg s 
moved to shm. It would make things simpler for tm callbacks and related 
routes (no need to move back/forward from/to pkg/shm). Parsing will 
happen always once, as now cloning to shm in tm discards some parsed 
headers, which may be needed in failure route or callbacks.

Cheers,
Daniel
