Hello everybody!

I have a high volume sms server 20k+ day, the thing is that i have been detecting that its not being efficient, and also when i added 2 more modems ( from 6 to 8 ) the increase in performance was almost unnoticeable and i dont know why, or what i can do to make it faster :S

Thanks

Typical time for sending one message is something like 8 - 12 seconds, but it depends on the network and on the length of a message.

Two more modems should increase the performance about 30 % on your system. Have you checked from the log how messages are sent and what is the sending time and how it varies? Also, has there been any errors?
