Troubleshooting Performance in SharePoint Online
By Anatoly Mironov
This is my personal list of links and thoughts on troubleshooting performance in SharePoint Online.
Resources
- @MSFT365Status, a twitter flow on the incidents and resolutions
- connectivity service
- Service Status (open for all), Service Health (for admins)
Health info in Response Headers
Every response from SharePoint Online contains some health information:
- Diagnosing performance issues with SharePoint Online (MSDocs)
- Troubleshooting SharePoint Performance Issues with F12 (blog post)
Following Response Headers could reveal the health:
- x-sharepointhealthscore, 0-10 score, the higher score the more loaded is the SharePoint Server.
- spiislatency, time in ms that the request waited to be processed by IIS. Unfortunately, I cannot see this value as of writing (2019-10-14)
- sprequestduration, time in ms IIS took to process the request. Unfortunately, I cannot see this value as of writing (2019-10-14)
