[OpenSIPS-Users] Can't get more than 5calls/sec?

[chris]

Hi,

It seems that the sipp receiver script is crashing, anyone have a decent
sipp send and receive script for a statefull opensips with record
routing?

Thanks

Chris

Chris,
      Are you currently using xlog to write messages to log file?  If
yes, make sure that you configure syslog to use asynchronous logging for
the log facility used by opensips.

Hi,

I assume you mean increase the log level above 3 when you say increase
the verbosity?

I am using a completely internal test rig on a LAN.

Running the Sipp instances back to back I can create whatever call rates
I like but as soon as I introduce opensips it dies after 5cps.

Have cut the cfg file down to a bare minimum just to route the calls
with rr with little difference.

Thanks

Chris

Try to increase the verbosity in the log and see what happens.
You should be able to push more cps than 5, unless you have something
wrong in you cfg, or your vendor limited your gw, etc.

Hi,

Can anyone help with a performance problem.

I have a very simple scenario that I am testing.
Using permissions to allow fixed gateway calls and sending them to
another fixed gateway.
No registrations, no internal users just purely switching calls from one
gateway to another.
I have accounting enabled but even if I switch this off it makes little
difference.
I am using Sipp 3.2 with the send and receive instances on totally
separate machines.
All machines are dual core Pentiums with 4gig.
Opensips is running with -m 2048 and 16 child processes log 3 but this
also doesn't seem to effect the performance.
I have the rr module running.
Basically I run the sip processes at 1 call a second and slowly step up
the rate (concurrent calls don't seem to effect the performance).
4 calls a second is fine and I can leave it running like that
indefinitely however soon as I go to 5 calls everything starts to fail
with retransmissions everywhere.
Most of the invites seem to eventually get through but all the byes stop
being processed.
Slowing the calls/sec down doesn't seem to help, only pausing the
transmission and waiting for everything to go quiet will allow me to
begin again without restarting or resetting anything.
Blogs have people running these at silly call rates so getting above 5
shouldn't be a problem.

Must be something basic that is wrong.

Any ideas?

Many thanks

Chris
