如何强制RAM编程？

Question

I am about to make batch program, and then compile it with BAT to EXE converter. If I am making program like

@echo off
set Line=0
:Start
set /a Line=%Line% + 1
echo %Line%
goto :Start

I see each time, previous number, +1.

This goes quite fast, but I can still follow sequence.

I know that computers are thousands times faster, since they have to calculate much much more for computer itself.

Is there possibility to force additional performance for program? Reserving RAM, or anything like it?

Answer 1

code, you can test:

@echo off & SETLOCAL
for /l %%i in (0) do <nul set/p=.

---

@echo off & SETLOCAL
:loop
SET /a var+=1
ECHO %var%
goto:loop

Answer 2

You can make it about a million times faster by using a real programming language.

In batch, you are actually executing plain text commands, which are individually parsed and executed by the command interpreter. This was never optimized for speed. A batch to exe convertor does little more than wrap the code of a batch file and feed it to the command interpreter, so it doesn't execute any (or at least not much) faster than a regular batch file.

Extra RAM doesn't mean extra performance by the way. Extra RAM only gives you extra performance if your application has too little RAM available to fit all its data in. If that happens, a part of your application's memory is swapped to disk, causing an extra performance hit. But there's not much you can do about that in batch anyway.

Many programming languages have compilers which convert your code to actual machine instructions, or at least instructions for a highly optimized virtual machine, like .NET or JVM. Even scripting languages like PHP are highly optimized, because they need to be able to execute large chunks of code in very little time. For batch, this is not the case. You're just missing the purpose of what batch is, which is repeating a lot of command line instructions, because you don't want to have to type them in every time. ;-)
