== Optimisation ==

Writing code which runs fast.

Consider having configurations which are read from DB frequently but written-to rarely, be set in configuration files which are written-out from the DB (like the CSS from themes)

 * If a specific inner-loop routine canot be optimised in Python, then consider writing a C routine for this use case.

{{{
for i in range(0, len(rows)):
     row=rows[i]
}}}
runs much faster than:
{{{
 for row in rows:
}}}
(0.05 vs. 0.001 seconds in my test case).
