There is a custom list with around 5800 items and a custom search page is built to query this list.
All of a sudden the performance of this custom search page has degraded, and is taking lot of time to fetch the results.
I suspect this to be an environment issue as there is no code change done recently and items in the list did not increase drastically.
Any help on what has to be checked in the environment is apreciated.
Thanks in advance.
