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 )</blockquote>
<br>
Does this loss refer to performance?<br>
<br>
<blockquote cite="mid:5638FB1A.5010103@b-and-c.net" type="cite"> 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>
</blockquote>
<br>
if you want to list what you had to tune, specially the tcp/tls,
then we can analyze if there were changes to those features or the
impact is from somewhere else.<br>
<br>
Cheers,<br>
Daniel<br>

Anyway, we are now satisfied with the performance, but any small
new gain is always good to get :)<br>
<br>
Best,<br>
<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>
</blockquote>
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>
