@ashokv Hi, is the Health Check present in your environment? If so I would suggest running it once and work on the High/Medium Risks related to the Record Type with which you are experiencing the slowness at the moment. This will really help you a lot in identifying the culprit as per my knowledge. You can actually see the objects flagged as High or Medium Risk in the Health Check Results that consumes long duration in order to execute.

You may go ahead with the suggestion made by @rodgraham or you may also opt for Grid Style Record Lists if you are making use of Appian 16.1 and above. Added to the reasons stated above, the issues could additionally lie in the List View and Default Filters of Record Type or the Database Entity(A view and it may be running slowly) that acts as the source of Record Type.

I believe it may be difficult at times to understand where the problem lies exactly without knowing the implementation details, so, as a last resort, I would suggest working with COE if you are on cloud or work with a person in your project whose role is more or less similar to an Architect.
