I've used accelerators - I even have customers who have them. IMHO, they 
make matters worse typically. A well configured Dual-PIII-450 running 
4.x-STABLE with a tuned kernel, and a tuned Zeus config can perform rather 
quick on it's own - sticking a squid box in front will, generally, cause a

Indeed, but it's not doing any local cacheing, so will not be using RAM as 
efficiently as it could be, and probably not as much.

Point taken, but the goal of the Apache project is not to produce the 
fastest web server on the planet. I think it's fair to say that they don't 
care about cacheing, because that isn't their objective. My opinion as to 
whether this a good thing or a bad thing depends on what application I'm 
setting up - I spend a LOT of time trying to do relatively clever things 
with PHP, and on limited resources. As a result, I need cacheing, and I need 
ot squeeze performance out of what I have. If I'm handling a low-traffic 
site with a few hundred Kb of relatively static content, I don't really care

Yup, and I've read it. Please don't think I'm criticising Apache - it's a 
good product and has been critical to the growth of the web in many ways.

My post was meant to reflect as to whether a web server was memory 
intensive, which Jeff seemed to think it wasn't. I just wanted to point out 
that Apache by default, isn't, but it could be. And anyway, high traffic 
sites on well configured servers WILL be memory intensive. I do also think 
that Apache could do with some tweaks mostly around performance, but only 
because I'd like something as powerful as Zeus, but without the £1,100 price 
tag and on-going maintenance contracts. :-)

Anyway, I'm at work today, so I want to finish up so I can go home and do 
some of this 'christmas' thing. Bah.
