Ok, here is a VBScript version of my test script:
filesizetest.vbs
code:
Dim filTest, sTemp, iTemp
Set filTest = CreateObject("Scripting.FileSystemObject").OpenTextFile(Wscript.arguments.Item(0), 1)
wscript.echo time
iTemp=0
do
sTemp=filTest.ReadLine
iTemp=iTemp+1
loop until filTest.atendofstream
wscript.echo time
wscript.echo iTemp & " lines"
filTest.Close
Please run it like this:
CSCRIPT scriptfilename.VBS testtextfilename.TXT
If you use WScript (the default when you just run whatever.VBS, the wscript.echo commands become msgbox() and it affects the times...
I ran that same 1.3MB file through this script and got:
02:55:24
02:55:25
30446 lines
hmmm... someone better quickly tell me why I should keep using KiX 
cj
P.S. Here is the KiX test script:
filesizetest.kix
code:
break on
cls
;
; OPEN file size limit test
;
while $filename="" "Filename: " gets $filename ? loop
? "@time" ?
open(1, $filename)
$i=0
do
$=readline(1)
$i=$i+1
until @error<>0
close(1)
? "@time"
? "$i lines" ?
beep
quit
