Hello Daniel,<br>
<br>
Thanks for the new pointers, we will try it !<br>
<br>
For the record, we are now able to obtain an almost identical
behavior ( still a loss of around 3% left ) by tuning:<br>
- tls parameters.<br>
- tcp parameters.<br>
- optimizations of the config file in many ways.<br>
<br>
Those optimisations/tuning were not necessary on 3.3, but it is with
4.2+.<br>
<br>
Anyway, we are now satisfied with the performance, but any small new
gain is always good to get :)<br>
<br>
Best,<br>
<br>
Tristan.<br>

Hi Daniel,<br>
<br>
Same config, same server, only kamailio version is different,
starting the timer in the beginning of the config, and ending it
just after the save("location").<br>

looking more at it, some few hints.<br>
<br>
Because the tls does quite a lot of memory operations inside the
ssl library, try with mem_join=0.<br>
<br>
Also, based on the work done by Camille Oudot, you can try with
tlsf memory manager, which ensures predictability of duration for
memory operations in all cases. f malloc can be faster for common
case, but in some corner cases (e.g., lots of tls connections
dropped at the same time) can be slower than tlsf.<br>
<br>
Cheers,<br>
Daniel<br>
