I have a server where it takes an hour to publish a workflow. I've had this issue since 10.2. I recently upgraded to 10.4 with no change. I have been working with LFC Support for 2 months now and have had no progress. While publishing, the server resources on both the workflow and database servers are minimal. I have "Enable the 'Validate Design' option for new workflows" unchecked. I've tried creating new workflows with one "Rename Entry" activity only, or updating existing workflows - still 1 hour. I've tried publishing from multiple PCs, and even from the server - same across the board. I uninstalled Workflow, deleted all the folders from the install directory, and reinstalled, Guess how long it takes now? Yep, an hour.
So my question is ... where else can I look to troubleshoot what's going on during this hour? I like to nap now while it's publishing, but the problem is, if I have 8 workflows to work on, I end up sleeping all day.
