I agree that the speed issue has everything to do with the number of jobs maintained.

In the past you had to keep the closed jobs if you wanted to refer to them. Now you can archive them to save them without having them mixed with the open jobs. Working with the shorter list of open jobs is much faster and easier.

Make sure the system option in Company profile is set to retain jobs in archive. On the Maintenance menu, use Delete closed jobs. Deleting from the job list will move them to the archive list.

In Plus you had to produce the report to get information, but Adagio Job Cost has a fast, and comprehensive inquiry function. Often when you are looking for job information, the Inquiry function will provide what you need. Use it instead of the slower reports.
