A user has a fairly new Mac OS X 10.9, 8 GB or Ram, MS Office for Mac, and plenty of HD space. A couple of weeks ago she complained about system performance being slow, specially in MS Excel and MS Powerpoint. I was able to see the issue myself, when she switched between apps to modify it took a minute of two for the application to respond. After following a couple of online links I decided to remove MS Office completely according the official documents and reinstalled it again. She said that it worked for about a week or so and now the system is slow when working in Excel, not as bad a before but she can notice the delay.
I noticed the RAM use during her workday is about 80-90% or her 8GB physical ram, could this be causing the issue? If so why is it that it only affects MS Office products? btw.... I had all updates for MS Office when she reported the problem first, after reading some online posts i decided to not install the updates when I reinstalled.
If anyone can shed some light on this it'd be greatly appreciated
