Autoit Gets Progrssively Slower the Longer it’s in a Loop

[XanzyX]

I wrote a code where I populated a one dimensional array of 250,000 elements. I have a For..Next Loop to search through that array and add key elements to another array. I found that the first 50,000 gets completes in about 20 minutes, 100,000 in an hour. If I leave the process run overnight, it barely gets to 200,000.  I’ve tried writing the results to a file after 10,000 but that won’t work either.

Is there any way to speed this up?

Probably. Post the current code so we can test and make suggestions.

Convert to use of a database.  Take everything out of memory.

Compile and run 64bit so your process can hold more real time memory (or does that not actually add much, I don't forget if it's a ton, or only like an additional 1 MB)

Not exactly a solution and more of a workaround but you could have a few second wait at the top of the script and once the script has been running too long run itself and then exit. But this is a very primitive and crude solution.

XanzyX,

The symptoms you are seeing are usually the result of using ReDim to increase the size of an array. This is one of the slowest functions in AutoIt and should be avoided as much as possible. You might like to take a glance at the Recursion tutorial in the Wiki - the final example and the paragraph below it entitled "A little added extra" explain how to limit the use of ReDim to a minimum when dealing with arrays of unknown size.
