What are the chances I will get similar performance using a stack and httpd
to process http requests ..... as i would using lc server ...... if the
performance is similar, i feel more confident building using this form
..... i'm not producing HTML code ..... just passing encrypted arrays back
and forth ..... as well as sending & receiving small small files.

that way i don't have to even run apache ..... just nginx and the services,
