Making a small change in one of the files and typesetting again results in a run of about 1 minute.

Howdy,

As Dick Koch said I also see no delay in processing your example with the pdflatexmk engine. Was this test file in the same directory as your other files? if so could there be a file in that directory that is causing a problem; e.g., a platexmkrc file?

You might also be having a problem with your system.

Good Luck,

Herb Schulz
