There have been a couple reports of people having some performance issues but nothing as bad as that.
What are the rest of your system details?
I'm using a Dell XPS420, 3.0 gHz Intel Core2 Duo, 4 Gb RAM, Plenty of hard disk space (1, 2 and 3
TB drives), about 1.5 TB free, ATI Radeon HD 4600 video card running a Dell Ultrasharp 24" display running at 1920 by 1200, Windows 7 (32-bit), Service Pack 1.
Does that help. I rebooted the machine (I realized that I hadn't since Creative Cloud installed) and it has run better, but I'm still using CS6.
This is reminding me of using InDesign 1.0 and 1.5 on a 486. I don't miss those days...
You mentioned, rebooting the machine "it has run better". Does it mean that the problem has gone away on rebooting and thereafter? Do you still face performance issues? Is this a machine where any prerelease build of IDCC was installed/uninstalled and cache/preferences not cleaned? Were any other applications running simultaneously when you first faced the problem?
I would strongly recommend that you wipe that machine, install more RAM (Max it out...RAM is cheap) and move to 64 bit. The recommendation for RAM for InDesign CC is eight gigs but that requires a 64 bit version of Windows.
