Need a bit more detail.

The 5120 is kind of a wimpy processor, but what is keeping it busy?

What do 'top' and 'htop' show are consuming the processor?

What is your application?

What are 200 calls doing?

Are you calling a bunch of AGIs written in scripting languages?

Eliminating translation is difficult. How do you know you were successful? 
Do 'module show like codec_' and 'module show like format_' show anything 
unexpected?
