Is this assertion regarded as true among all expert software developers or is it simply the developer's own experience?
Given a single, adequately equipped Apache server using the Linux operating system and two functionally identical web-based applications - one written with PHP5 and the other written with Cold Fusion (all other things like databases, etc. being equal) - how is the "simultaneous user capacity" determined for each of the two versions of the program (without; of course, hiring thousands of testers)?
What RAD-type language is known to be the most scalable for web-based applications (all other things like databases, etc. being equal if other things are used in the applications)? It is known; of course, that PHP is not a RAD-type language.
In another forum an expert software developer has stated that PHP programs do not scale well (i.e., capacity of handling many simultaneous users). The same expert software developer stated that web-based applications written in other languages such as "Cold Fusion" are significantly more scalable.
maybe he doesn't know that Yahoo runs in PHP
2. not a possible comparison, coldfusion runs coldfusion server, to my knowledge it can't run without it, therefore the comparison is impossible because all other things cannot be equal
you could look through this
the Criticism section is good
3. There are RAD dev tools for PHP, Perl etc

In my experience, which is not extensive, working with coldfusion servers and expert coldfusion programmers is that it is junk when compared directly with apache running mysql with php or perl. This was confirmed by those expert CF programmers as much as my own investigation.
keep in mind that software of any kind is only as good as the people who make it, the language is less often at fault.

- I think - is the query that produced the citation.

if you're just starting a project, don't pick the language based on some percieved notion of a need for speed. It's very unlikely you'll reach a point where that kind of scalability will matter. Instead, go for language power, and ability to find peers to help code. (I'm a fan of Haskell and Lisp, but the number of people familiar with them is pretty low.)
But let's assume you've succeeded against the odds and managed to achieve popularity. What languages scale well? Let's look at examples of popular sites and what they're written in:
Okay, okay, I'm cheating a little by excluding certain information. What I'm not telling you is how much hardware each site uses, or how much each site delves into low-level machine code to accomplish certain tasks; neither of which I know. LiveJournal, Wikipedia, and Google all definitely use lower-level programming where it suits them (e.g., C, ASM), and I'd be surprised if MySpace didn't. Ultimately, speed comes from the algorithm, not the language.
Essentially, my point is that jatar_k is right: "software of any kind is only as good as the people who make it".
