Hello,
can you use benchamrk module to see if any part of config got slower? if
executing of config from beginning of request_route to save() is more or
less the same, then setup of connection could be the issue.
Since 3.3., there was some work on usrloc module about gruu/outbound and
doing unregister if the tcp/tls connection is lost. On tls module, there
was some work for SNI. In tcp core, some callbacks were added for
websockets. If I haven't missed something relevant, I can't imagine what
would create this handling issue between the versions.
Cheers,
Daniel

Hi Daniel,
It is on the exact same server, same system configuration, same
configuration trimmed down for fitting 3.3, packages installed from
the kamailio debian wheezy repository.
I can reproduce it just using sipp and a simple REGISTER loop.
Do you want me to run some specific tests ? provide you some specific
traces ?
Best,
Tristan.

Hello,
is the same operating system and server, or are you using some other
machine for the new version? I can't remember right now any big
change in tcp/tls side, besides sni, which should not have any
relevant impact as described here.
Also, have you installed from git branch 4.2 or the tarball/packages
of 4.2.6?
Cheers,
Daniel

Hi List,
I've been reaching a strange thing lately, trying to upgrade to kamailio
4.2.6 ( identical config ):
- 35% loss of performance on TLS connections ( Sipp REGISTER scenario,
easily reproduced ).
- more TCP workers needed to ease the TCP queues ( 32 workers on 3.3.7,
at least 64 are needed on 4.2.6 to avoid "queue full" messages in logs ).
- kamailio 4.2.6 intermittent processing of requests ( Kamailio stops
accepting new tcp connections, then resume a bit later, then stops
again,... ) => starts happening when Kamailio is treating more than 20k
tcp connections, with between 500-1k req/s. During those periods, trying
to connect to kamailio with an openssl s_client -connect will end up in
a timeout or with a long delay before the certificate is received ( 03
CONNECTED ).
- kamailio 4.2.6 dropping connections, kamailio 3.3.7 keeping those
connections: after a while, the number of active connections starts to
decrease on kam4, on kam3 it stays constant.
I was wondering if I was alone in this situation or if someone else is
impacted, has some advices ?
It does not seem to be a config issue, as it is the same that was
deployed with both versions.
