[OpenSIPS-Users] opensips taking too much time to load

[darin vivekanadan]

Thank you for you help and hint.
Indeed domain name was the problem and culprit for the delays. When I replace the domains with IP, it just took around 1 sec to reload gateways. In our case we cant get rid of domain names so this is what we did to improve the timings.
So any time before executing fifo dr_reload we do nslookup on the domains in the table. That does DNS caching on our local system. That cache help opensip to reload gateways in 2-20 seconds. While nslookup itself takes anywhere between 30 sec to 3 minutes. So on average now dr relaod takes anywhere between 30sec (Best case) to 3 min (worst case). Much better that 8-10 minutes.

Again thank you for you help for checking the typos and reread it.

Regards
Darin

15K prefixes is not really big deal - so try only with the IP gws and check the results.

The transactions stats have nothing to do with the number of
      parallel calls and it seems you have only 5 transactions in mem -
      the UAS_transactions is a counter (not a real time value) so it
      gives you have many transactions you had from the opensips start.

We can try that. Also did not mention that we have around 15K entries in dr_rules routing to those 5K Gateways.

                    many active call slow it down? Cause my transaction
                    stats looks like this.

                  have to DNS resolved at load time - depending on the
                  DNS response time, this may take some time.
