Our SharePoint site is going extremely slow, especially when trying to delete items - majority (90%) of triggered Workflows fail and give Error Occurred - Editing or adding data is a nightmare.
What could be causing the issue ? Any troubleshooting steps to follow ?
Our memory usage is between 70 and 80% and won’t lower even if we stopped loading or editing large volume of data.
Is there a possibility to figure out where the traffic is coming from ( Site/ crazy Workflows)?
We have around 30 Lists ( contain average of 15000 items each).
