High Cpu Usage After Converting Small Script

[ken82m]

I have a script I wrote in version 2 which simply monitored for some files I had it running as a service. It might jump up to 1% in task manager when it found a file and renamed it but otherwise it was always at 0.

I converted the same script to version 3 and now it's taking 25% of my cpu while doing nothing (just watching for the files). Any ideas? Here's my code.

V2 (Low CPU Usage):

SetEnv,PDFRoot,C:\\CreatePDF\\

SetEnv, SourceFile, CreatePDF

Setenv, Ext,.PSF

Loop:

SetEnv,Random,

SetEnv,Source,

SetEnv,Destination,

SetEnv, PrintSource, 0

IfExist, %PDFRoot%%SourceFile%1%Ext%, SetEnv, PrintSource, 1

IfExist, %PDFRoot%%SourceFile%2%Ext%, SetEnv, PrintSource, 2

IfExist, %PDFRoot%%SourceFile%3%Ext%, SetEnv, PrintSource, 3

IfExist, %PDFRoot%%SourceFile%4%Ext%, SetEnv, PrintSource, 4

IfExist, %PDFRoot%%SourceFile%5%Ext%, SetEnv, PrintSource, 5

IfExist, %PDFRoot%%SourceFile%6%Ext%, SetEnv, PrintSource, 6

IfExist, %PDFRoot%%SourceFile%7%Ext%, SetEnv, PrintSource, 7

IfExist, %PDFRoot%%SourceFile%8%Ext%, SetEnv, PrintSource, 8

IfExist, %PDFRoot%%SourceFile%9%Ext%, SetEnv, PrintSource, 9

IfExist, %PDFRoot%%SourceFile%10%Ext%, SetEnv, PrintSource, 10

IfNotEqual,PrintSource,0, Goto, Rename

goto, Loop

Rename:

Random, Random, 100, 900

Setenv, Source, ToConvert%Random%.PSF

Setenv, Destination, ConvertedPDF%Random%.PDF

Runwait, %comspec% /C "ren %PDFRoot%%SourceFile%%PrintSource%%Ext% %Source%", %systemroot%, Hide

FileAppend,%PDFRoot%X%Random%Y%Source%Z%Destination%\n,C:\\CreatePDF\\Queue.txt

goto, Loop

ENDPGM:

exit

V3 (High CPU Usage):

If FileExists($PDFRoot & $SourceFile & "1.PSF") = 1 Then Rename(1)

If FileExists($PDFRoot & $SourceFile & "2.PSF") = 1 Then Rename(2)

$Random = Random(100, 900)

$Source = $SourceFile & $1 & ".PSF"

$ToConvert = "ToConvert" & $Random & ".PSF"

$Converted = "ConvertedPDF" & $Random & ".PDF"

FileMove($PDFRoot & $Source, $PDFRoot & $ToConvert, 1)

$file = FileOpen($PDFRoot & "Queue.txt", 1)

FileWriteLine($File, $PDFRoot & "X" & $Random & "Y" & $ToConvert & "Z" & $Converted & @CR)

FileClose($File)

EndFunc

ahhhhh perfect thanks

I'm actually monitoring for printed postsript files. It's not perfect sometimes if you print two small jobs too close to each other they overwrite but it works.

You don't know of anyway to monitor the port or the printer in windows? Something more efficient than just checking for files every 1ms
