SharePoint Online List performance issue, when i click on new item or new form i face delay in opening new form. I was wondering how improve the performance of the list library. I have more than 1k items in this list.
For list performance, common steps are like below, have a try:
- Add indexes on columns.
- Edit the view and apply filters. Make sure only a portion of items will get diplayed under the current view.
And commonly 1k items shall not have sever performance issue which will cause delay on opening new form. Are you using a heavily customized list form? Or you have a huge number of columns?
