Very slow performance when querying a large number of tasks via the API.

For instance:
- querying when result set is zero or one task typically takes 60ms-200ms
- querying when result set is 100+ tasks is >5 seconds
- querying when result set is 200 tasks is 7-15 seconds
- querying when result set is 800+ tasks is up to 60 seconds

These timings are all taken from calls to the ITaskQueryService.queryTasks() function.
