We need your Expert Advice for Improving the Performance of the QTP,
Suspect –(Possible Causes)
We would like to know , if the below mentioned setting would affect the performance of the QTP scripts in any way?
We are currently having the 2 major vbs files in QTP Scripts. Each vbs File has around 17000 lines of Code with around 160 functions. And these are loaded at the Beginning of the Automation scriptrun (Not Run Time)
And we load shared Repositories at the start of the QTP run which is about 20MB.
Will this below Corrective action Help?
if we implement the below changes,  will be any considerable improvement in the Performance ?  
By  reducing  the No. of lines in the VBS file by splitting the 17000lines VBS File into smaller Files
 by loading the Functions and the Repositories in the Run Time Dynamically.

Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Do a malware check with several malware scanning programs on the Windows computer.<br>
Please scan with all programs because each program detects different malware.<br>
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
