Just switched from Windows 7 Home Premium to 8.1 Pro and suddenly my scripts which write a lot of text are 5-10 slower writing. I built a test and confirmed it is slower than a similar yet inferior machine. My new Windows Build has very fast Passmark scores.

Code:
alias SpeedWrite { var %1 = C:\Users\Public\Documents\SpeedWrite.txt, %2 = 1, %3 = $ticks | if ($exists(%1)) { .remove -b %1 }
  while (%2 < 200) { write %1 $str($r(A,Z),999) | inc %2 }
  echo Complete: $calc($ticks - %3) $+ ms
}

The only difference being 8.1? How can i resolve this slow write speed...

Thanks for your bug report. I don't have Windows 8, however the method for writing files is identical on all versions of Windows, so that will not make a difference. Testing under Windows 10, each run took around 1700ms. I then turned off Windows defender anti-virus scanning and it dropped immediately to 250ms. If you do the same, does that resolve the issue?

This is my first time ever enabling Windows Defender. Thus I've never experienced this. Is there a way to give mIRC the green light, so Windows Defender can be on without this lag.

I'll answer my own question:
In Windows Defender Settings > Excluded processes > Browse to mIRC Folder > mIRC.exe > Add

Problem Solved.

Similar fix in Windows7 with Microsoft Security Essentials. I added a time-echo above the while-loop, and found it often was even slower to delete the existing speedwrite.txt than to write the 200 lines to it.

Once I added the write folder to Settings/Excluded-files-and-locations, the speed was much faster. At least in MSE, the change in write/delete speed is inherited into subfolders too.
