Performance Penalty In Loops?

[flyingboz]

I have a piece of code that performs

filereadline, StringSplit, and filewriteline until EOF in a while loop. The first 1000 or so iterations occur at or better than 1 line per second (i'm using traytip to display the value every time a particular case is met, which in my data, is usually

every 5 or so lines). Performance (all things being otherwise equal on the same machine) appears to degrade the higher the

line number being read - when I'm reading line 5000 it is taking on the order of 10 seconds per line.

Before I went hog wild debugging and generating all kinds of timer information,

just wanted to know if some true developer type knew of a theoretical reason

why this should occur using AutoIT 3.0? (Ain't it great to be able to say that!!!)

If needed, I will happily pull all pertinent info together and post over in the bugs forum -

My memory consumption is not going through the roof, and I am not building any multidimensional arrays in memory as I go, all loop variables are flushed or overwritten each pass.

Out of curiosity, are you implementing any sleep() commands in your script?

If not, you may want to throw in a Sleep(10) at the end of some of your main loops. This will allow the computer time to execute other processes, that may be causing a backlog on your system.

Thank you both for your comments.

I have tried as Larry suggested using fileread() instead of filereadline() , w/ similar performance issues as the loop progresses. I have posted the offending (though otherwise functioning as designed) code in the v3 support forum.
