Any experienced users of the external program "prg" mechanism  of Rewritemap who use a compiled binary file as opposed to interpreted language?

Is there an appreciable performance difference on a high volume site, even when the program is simple? Such as the dash2under.pl example on the Apache documentation page?

Or if the script has a single line executing a "getent"

Using prg on a high-volume site is discouraged, as all requests will be fed through a single instance of the prg, creating a significant bottleneck. The dash2under.pl example is just that - an example - and there are better ways to accomplish what it does ... as there are, usually, better ways to accomplish things that prg can be used for.

Consider mod_lua as an alternative way to do rewritemap-ish things
