Okay guys - there is a lot of misinformation going on here. To clear up a few things:
In a pure apples to apples comparison, yes, Java will most likely be faster. For example, if you do a Fibonacci sequence generator in Java, it will most likely be faster in Java than CF. Reason being that ColdFusion is a dynamic language, whereas Java is static. So ColdFusion has to write a lot more byte code than straight Java will need to. This will be true for any dynamic language that is compiled to bytecode on the JVM, simply because it needs to manage the dynamic nature of the variables and methods that pass through it. So the statement of "they are compiled down to bytecode, so they are just as fast" is actually incorrect. It's a question of what the bytecode is doing and how much bytecode is the million dollar question. Now - the statement of "Cold Fusion is written in JAVA which means, generally, that a ColdFusion program will run slower than a program written directly in JAVA..... If speed of the application were the primary consideration, PHP or JAVA is the clear choice.". I say that this is incorrect as well, for a few reasons: 1) As people said, if speed is a primary consideration, write in Assembly. 2) The programming language is 99% time never the bottleneck in the an application. It's usually aspects such as the database. If speed of the application is the primary concern, I'd be far more interested in horizontal scalability. 3) I'm not sure where they get the stats that PHP is faster than anything else? That seems like a weird statement. I'd be curious about the numbers to back it up. Hopefully that clears things up.
