About a year ago I started a topic here concerning the fact that OmniGraffle was taking 28 seconds to launch. I was advised to strip some preference files out of my Library. In the midst of all this, Omnigraffle started working OK, so I dropped the subject. Shortly after, the problem returned and has darkened my use of Omnigraffle ever since.

So I decided to make a thorough effort to find out what was wrong. In the interim, I had installed an SSD drive for increased speed. But OmniGraffle was still taking 28 seconds to launch.

So I stripped out the folder "The OmniGroup" from my library. To be sure, I also deleted all these files:

Library > Caches > com.omnigroup.OmniGraffle
Library > Preferences > com.omnigroup.OmniGraffle.plist
Library > Preferences > com.omnigroup.OmniGraffle.plist.lockfile
Library > Saved Application State > com.omnigroup.OmniGraffle.savedState
Main Library > Application Support > OmniGroup

Then I restarted the Mac and launched OmniGraffle. No change!
But I *did* learn something interesting. In Preferences, I unchecked
Startup: Create a new document if nothing else is open.

When I launched OmniGraffle, it came up in a flash. BUT when I used Cmd-N to create a new document, it took 25 seconds to reach the dialog box. So that's the problem: creating a new document consumes 25 seconds. This sounds to me like a heap thrashing problem; is there some user-adjustable number in OmniGraffle that specifies the amount of RAM set aside for the user? Perhaps that got screwed up.

Anyway, I now have a workaround: I keep a new document up at all times. Unfortunately, I still have to wait 25 seconds if I want to create a new document.

BTW, I'm using OmniGraffle 5.4.4, but this problem goes way back.

I'd really appreciate it if you fellows could figure out what's wrong here.
