[SR-Users] Limit the number of requests per second based on the user

my last mail was probably not really clear. I don't want a pipe for all
users together, but one for each user. What I wanted to say is, I don't
need different limits for some users, they all share the same limits. I
have implemented the htable version now, and it's working as expected (when
considering the garbage collector timing). Could the performance decrease,
if the garbage collector has to clean thousands of entries from the hash
every 20 seconds?
With your new solution, I guess there would quite a few thousand pipes in
memory (since they don't get destroyed) in our scenario. Up to how many
pipes is Kamailio able to handle?
Best Regards and many thanks,
