[SR-Users] Subscribe load issue in kamailio

[Premchandiran]

Hi ,

I am working on Kamailio 4.0.1

We are trying load for presence subscribe with 1 cps(calls per second) using
sipp , our setup is as below

 

No of children in both proxy and presence server is 4

DB mode is 3 in presence server 

Expires is set to 3600 in subscribe request

May I know how many cps is  supported for presence?

Please let me know why load is failing.  

 

Machine-1                       Machine-2
Machine-3
