How many concurrent calls are transcoding?

Load average isn't always a good measure of cpu utilisation. Traditionally 
it just means the number of processes that are running (or waiting on IO) 
averaged over a period of time.

Transcoding to/from complex codecs (g729, gsm) requires CPU usage. Ye 
canny change the laws o physics... However you can buy hardware 
accellerators.
