[erlang-questions] OTP Efficiency

[Max Lapshin]

I've also tried to work without OTP and there have been left only two
places in my code, which are not OTP:

1) gen_server:call changed to implementation without additional
erlang:monitor, because caller already has monitor.
It reduced load.

2) media_ticker is a process, that retrieves frame by frame and sleeps
for the timestamp difference. It happened to
be easier to make it very small without otp
