Let's get one thing out of the way first - the single largest speed boost for Perl web applications is mod_perl. Everything else is second.
in reply to When to use templates?
My rules of thumb for using templates are:
- If I intend on making more than two changes to any part of the system in the next year, I will want templates.
- If I ever want to output the same page in more than one format, I will use templates.
- If I ever want to support more than one language, I will use templates.
- If I ever want to have someone else working on the same project, I will use templates.
In other words, I will not use templates if:
- I will never make any changes
- I will only ever use one format
- I will only ever use one language
- I will be the only person to ever work on this
In other words, I have never seen a reason to avoid templates. :-)
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
