I experience big differences in load times of ID depending on when it is opened.
If I load the ID app after starting the computer, it takes about 1 minute 40 seconds to load. If I then load a six page document, it loads in about 10 seconds.
Next, if I quit ID and open it again, the load time for the app is only about 40 seconds.
If I restart the computer, the load time for ID is back to the long load time of 100 seconds.
If I click on a document after starting the computer, it takes about 2 minutes to load ID and the document. If I close that document and reload it, the time is just 10 seconds.
To add to my frustration, after starting the computer I can't use any function for over 2.5 minutes because of how long it takes CC to quit hogging all the computer resources until it finishes loading.
Is there a question here someplace?
What's your OS and version of ID?
ID always takes long to load on the first start after a computer boot.
As for whether or not you are experiencing normal times, without knowing anything about your system, O/S and the files, it’s impossible to tell.
Bob is correct. The first load after a reboot, InDesign caches a lot of information. On subsequent loads, it loads considerably faster.
