As reported by Juan Priotti
[here](https://lists.kamailio.org/pipermail/sr-users/2017-December/099727.ht… the way
pipelimit actually works is:
limit * timer_interval = max req/sec
However the [module
documentation](https://www.kamailio.org/docs/modules/5.1.x/modules/pipelimi…
can be interpreted as:
limit / timer_interval = max req/sec
Is this just a documentation error or are we doing something wrong?
Thanks.

Hello, there have been two changes in January 2018 to this module (1880f1f8be4b51ce and
407b257d4ef56730e04). Here the internal logic of the module was changed, it works now
different. Have a look to the git master or 5.0/5.1 branch to get the idea.
If you still see an error in the documentation, please re-open this issue.

We're using version: kamailio 5.0.7 (x86_64/linux) 743c2d and pl_check() using
TAILDROP algorithm is only triggered when the pipe counter is greater than
"interval" * "timer_interval".
Example:
```
modparam("pipelimit", "timer_interval", 3)
modparam("pipelimit", "hash_size", 10)
modparam("pipelimit", "db_url", DBURL)
modparam("pipelimit", "reply_code", 503)
modparam("pipelimit", "reply_reason", "CPS Limit reached")
if (!pl_check("$si", "TAILDROP", "20")) {
pl_drop();
exit;
}
```
Result: pl_check is only triggered when "PIPE: id=10.0.0.2 load=0 counter=61"

@rogelio-telnyx - can you try with the patch from commit fb408fb and see if it fixes this
issue? Patch was intended more for #1675, but might be what is needed for this one as
well. If not, I will look more into this one.

@miconda I will try with the patch from commit fb408fb and confirm results. In the
meantime can you confirm if it'd be feasible for Kamailio to work with pipelimit's
timer_interval set to 1 second or if that can cause performance issues? Thanks

It is how most of the deployments are out there, so should work fine. Only if you have a
deployment with heavy/lengthly timer tasks, you have to start offloading the main timer.
This can be done also in other modules, like usrloc, htable, ... by setting their mod
params to use own timers -- usually this is controlled via timer_procs or timer_mode mod
params of each module, but to be sure check if there are other timer related params in the
readme of each module.

Closing, a patch was pushed long time ago. If another issue happens, open a new one.
