Python v COBOL

[wavic]

If you read the description, all of the time critical processes of this application
are written in 'C':

The server is written in hand tweaked C trying to take advantage of modern CPUs. It relies on picohttpparser for header & chunked-encoding parsing while uvloop provides asynchronous I/O. It also tries to save up on system calls by combining writes together when possible.

I didn't miss that. It's OK. So many Python modules are written in C or are wrappers around some C library.
