I want to use FreeSWITCH solely as a T.38 modem on a Windows server. I have a Lua script that accepts fax calls and, at the end of each call, saves the call information to a file for my software to process.
However, with around 100 sessions, FreeSWITCH maxes out the CPU of a t3.xlarge AWS instance. In contrast, I have a closed-source third-party T.38 modem software that, even with 300 sessions, barely affects the CPU usage of the same t3.xlarge machine.
Are there specific modules I should disable to make FreeSWITCH lighter? Do I need to run it on Linux? My concern is that if it’s so CPU-intensive on Windows, even if Linux performs better, it still doesn’t seem very efficient.
Any advice would be greatly appreciated!
