Using dynamic printing has many advantages concerning performance issues. For debugging print performance issues, it is sometimes useful, to review the dynamically generated SynPlotService.mxd. Usually the SynPlotService.mxd gets emptied after the print output is generated, but using the client side debug console, the MXD equipped with a timestamp is stored. Steps to do are:
•Open the project
•Click into the status bar
•Press Ctrl + Alt + D to open the client side debug window
•Check the option "Display Cache- and Extent Information"
•Generate the print output
•Browse the target ArcGIS output folder of the main map service (c:\arcgisserver\arcgisoutput by default)
•Folder will contain a file called dynamicWOprint_<timestamp>.mxd
