Powershell Script taking too long - powershell-4.0

Question

I have a powershell script which involves creating multiple directories and command used to create directory is New-Item -ItemType Directory -Force -Path "abc\WEB-INF\classes\".
Log for creating directory path shows that it took 50 seconds(15:36:42 , 15:37:32) to create 2 directories(WEB-INF,classes).This behaviour is completely abnormal.Is there any other way i can create directories to save time.

Answer 1

Got the bug . It was not actually the command which was running slow. I was using
Start-Transcript -Path "abc\def\ghi.log" -Force -Append
which doesn't check whether directory (abc\def\ghi) exists . It gives below log but commands run after will be run slowly till Stop-Transcript
Transcript started, output file is abc\def\ghi.log
