Unfortunately "Save as pdf" is not (yet?) supported on Server.
If your are using a Mac you can use the Save as PDF option in the print dialog box instead. This is noticeable quicker than Save as PDF. I'm not sufficiently familiar with Windows, but I assume there is some sort of equivalent there too.
On Mac you can use MBS Plugin functions to redirect printing to PDF file.
For Pro and Runtime.
I guess OP has PSOS'ed a script producing a PDF and is still waiting for its output
it must be a coincidence.
Yesterday I developed scripts to inform my users about the fact that report generation might take up to a few minutes.
Today Filemaker release Filemaker Por (Advanced) 14.0.6 with an update of the PDF Generator.
PDF's are now generated about 10 times faster than yesterday: wow.
Install that update!
I can confirm that. I just ran the same pair if tests I mentioned earlier (Save as PDF and Print to PDF) and this time they were both produced in the same time.
On WIndows, I sometimes use the Bullzip print driver which has many other features as well, and is pretty fast.
