problem generating pdf

Good morning. I have an application in which I generate weekly I send them in pdf format through an action and a workflow. These pdfs can be downloaded from Google drive. it worked perfect until a few days ago. On Monday I noticed that it is taking time to generate the pdfs, approximately 100, several days. Today I did not finish generating the 100 pdfs, it was 22. Before I was tame a few minutes.

Please contact for help with this.
