SharePoint Break Fix to Solution

Slow performance of SharePoint 2013 site and gets timeout with error on webparts: 

correlation ID: 00000000-0000-0000-0000-0000000000

Cause:

webparts settings are using xslt to manipulate search results and its view. So its taking time to load and shows timeout with above correlation id.

Steps to fix:

1. Login to Web front end servers

2. Check current timeout settings using PowerShell:

$myfarm = Get-SPFarm

$myfarm.XsltTransformTimeOut

3. Change its value to 5 seconds(reasonable as per page customization)

$myfarm.XsltTransformTimeOut = 5

$myfarm.Update()

Refresh site page and check if issue still exists.
