Re: Witango-Talk: Boosting Server Performance, and TCFs

To some degree I guess it would work as a mini virtual machine. Take RealBasic for example. It allows me to write code in a much simpler format than C, or C++, yet I don't have to deal with pointers or garbage collection. The IDE has a built in compiler that compiles the code into native platform code, just like if it was a C app compiled in code warrior or something. The resulting app is faster in most cases than the same apps in Java, because it is native. The drawback is that RB cannot give you all of the optimizations possible if you wrote in C from the start. So the same app written in C to start, may run faster, and definitely have a smaller footprint than an RB app. The same is true if you compare an app written in assembly language, vs. C. The assembly app could be more finely tuned, and run faster and have a smaller footprint. It is a tradeoff between optimization, and development time.

Since Witango does not have to worry about a gui, or control objects, but just process data, I imagine a compiler written for the Dev studio to compile TCFs would be easier than what a language like RB has to do. But I have no experience in what it would take to write a compiler, so I may be speaking out of school.

Hi Robert,

I guess this is where my expertise drops off.

Wouldn't the Witango Server then have to operate like a mini-virtual machine
of some sort?

The Witango Server is currently just an executable for it's own code, with
the ability to process external "scripts" (a.k.a. TAF, TCF, TML files) and
return the output, which is why we have this wonderful interpreted language
(Witango) in the first place.

Converting code for use in an external Virtual Machine or CLR is one thing,
but creating a whole new is another. Wouldn't we then loose the advantage of
making our TCF Classes accessible by other external applications?

Like I said, my experience doesn't take me this deep in the world of
programming, so maybe I'm loosing sight of your objective here.

Would the phrase "self-compiling" be more along the lines of what you are
talking about?

The only "self-compiling" environment I know if is the Mono-Project, which
is an Open Source initiative to port the .NET Framework to *unix platforms.
The compiler used in the Mono-Project is written in C# and can compile
itself and other C# code - all on *unix. http://www.go-mono.com/

So, I suppose it's possible.....

Just because our tafs would be compiled in some native
format, doesn't
mean we would have to start worrying about things garbage collection.
The compiled tcf would would have in/out points and process data
within. It would run within the memory space of the witango
server, and
the server would handle the garbage collection and the nasty
stuff. The
main benefit would be that complex methods in a tcf would not be
scripted, but compiled so that there would be no tag
processing and the
other performance drags that are inherant with an interpreted
language.
It would mean, though, that certain things you can do in a
tml or taf,
you could not do, like dynamic referencing.

support
this kind of low-level environment (nor any interpreted

that
matter, e.g., ColdFusion).

For example, garbage collection and other memory allocation
issues - 
what
sort of Metatags would we need for this?
