Hi Rob. Here's how you design an e-commerce site: Figure out how many users you want to service. Figure out how much juice it takes to service each user. Multiply. Add 50%. Build. You simply cannot come forward and say, "look, I've got this big-assed linux box, why is my site sucking?" We don't know, and it's neither our job nor our business to know. I saw many very, very good explanations on the 'edge of chaos' thread, a couple of which actually led me to make some tweaks on my own site. I'll try to recap it: You should never be anywhere near any fine line - the risk is just too great. Swap kills web sites. Queueing kills web sites. People looking for 'graceful degradation' in a production web architecture are looking for the wrong answer. Unix is not designed to degrade gracefully - Linux even less so. They are both designed to go balls-out as long as they have CPU and RAM space to do so, and that's what they do. The very, very best minds in production architecture out there will pine over how much accessing data from RAM sucks - they want all cache, all the time. There is not a linear falloff in performance from cache - RAM - disk, and you should not expect one from the applications which rely on those things. The httpd.conf file is extremely well documented. There is a program in $APACHE/bin called 'ab,' and will give you a decent baseline from which to provision for your site, and etc. If you have a specific problem, and ask a specific question, you will get, usually, an outstanding answer, with as much technicial depth as you care to probe for.

Anyone who uses Linux knows how horrible it is on SMP, I think some tests showed it uses as litle as 25% of the second processor.. A simple benchmark with 'ab' shows the number of requests per second almost double when the concurrency is increased from 1 to 2. With a concurrency of 4, the number of requests per second increases to about 3.2 times the original, which is not bad at all considering that these are dynamic requests with DB queries. Eh, ab isn't really made as anything other than the most coarsely-grained of benchmarks. Concurrency testing is useless because it will measure the ratio of requests/second/processor, not the scalability of requests from single to multiple processors. IOW, you would see almost exactly that same increase in req/second on a single processor, most likely, unless you have a really slow machine. You'd have to tune your load to give you one req/second/processor and then go from there for it to mean anything.

It depends on how often your perl is called. if it is very
infrequently, then it is not worht it, but if perl is used often, you
will get a big win.
never forget the infamous 'perl creep' effect on web sites. if you have
one perl script, it will multiply until you are faced with a tribble-like
plethora of perl scripts.
best to code them with mod_perl early on so you're prepared for it in the
