Hello!
Today I tried to statprof my toy application, that uses htmlprag
since it is too slow (4 sec on one page) vs 0.5 with Python.
Statprof says, that most of time takes `eval` function, but I checked
htmlprag source --- it does not use eval. So question is where is it
called and what can I do to speedup my application?
PS. Should I attach source file and html file to parse?
