Word of the day: ultracrepidarianism Of course, financial investors are experts in the field of backend systems. One in this situation wishes your client would pick up on that. The fact that he's comparing mod_perl (an Apache module) to an Apache module should be a glaring sign of said investor's utter cluelessness. The fact that he's even mentioning CGI versus a server API-level module -- well, I'll stop now before I embarass someone. > If anyone on this list could forward any resources > that do comparisons along these lines, or even analysis of mod_perl's > handling of high-load web traffic, I would be very grateful. Whether C is more efficient than a RAD language like Perl (or Python or PHP) is an incredibly stupid question, because one with sufficient knowledge should know already that the answer is yes. The real question is whether said efficiency is worth the arduous hassle of building the app in C. Considering the speed at which modern servers execute interpreted or JIT-compiled languages, that answer is almost always no. There is "fast", but then there's "fast enough (and finished developing in 25% of the time)". They'll have to decide what's more important. Now, as for case studies, here's a quick list: http://perl.apache.org/sites.html And then this article, outlining how mod_perl was used to build the eToys site: http://www.perl.com/pub/a/2001/10/17/etoys.html And now for a completely shameless plug: http://www.iqcoordinator.com/ Which is a processing-intensive work order management system, built entirely on mod_perl. (Some day I will write an article myself :) Our systems don't even break a sweat. Actually, mod_perl saved us from having to buy more hardware. It's plenty fast. - -- Stephen Clouse <[EMAIL PROTECTED]> Senior Programmer, IQ Coordinator Project Lead The IQ Group, Inc. <http://www.theiqgroup.com/> -----BEGIN PGP SIGNATURE----- Version: PGP 6.5.8 iQA/AwUBPBpphQOGqGs0PadnEQLW2gCdGonCCAU0aCauPTTsIZMvzcWU1mIAnj3J BBNeCw2RdSN90qTCYDFLUYPP =Exa7 -----END PGP SIGNATURE-----
