well... you're asking why opening a process in python rather than doing it
directly takes more time. no wonders there: of course it takes more time!
Especially if your process writes lots to stdout/stderr that python needs
to collect.
BTW: never ever ever run ANY external process from the webserver: you could
easily be DDoSed AND you incur in lots of issues (random timeouts, memory
issues, leaks, and aforementioned slowness).
