scripts and speed

[ronnie gauthier]

I need some advice on a script I'm developing.
The script is perl from flat file. If the site does well a port to Msql
is in order.
the srcript will do ski resorts in states, chat, calendar, news insert,
specials, banner, and stats for each resort. 

The ?.

If the site gets heavy usage would I get any significant speed
advantages by breaking the script into smaller module scripts?

thanks

Ronnie
