Checklist when performance has degraded recently

Theatre Manager performance should not degrade over time given a constant set of environmental conditions. Meaning, if I have the same number of users doing the same amount of work at at given time, then each user should see performance remain at the same level.

Sometimes we are asked to identify why Theatre Manager has slowed down, or is slow after it has been installed. In almost all cases, the issue is not Theatre Manager, but some setting that has changed on the network, on the computer, or on the server. The following list contains the 'usual culprits'. Please check to see if you have been affected by one of them should you experience an abrupt change in behavior with Theatre Manager.

Finally, we are not expecting problems to occur. Usually things just run. But sometimes it is possible for things to awry and a checklist of possible culprits is useful.
