gkfahnbulleh,
I honestly don't know what those letters mean. Maybe you can enlighten us. As I mentioned, the phrase 'database caching' was posted in another forum by someone apparently having the same problem as I am.

But the question that gnaws at me is: Why does an entire office encounter consisting of two pages of text take 14% of CPU usage to save, but a single line of an inbox message takes 100% ? The delay adds up to several precious (annoying!) minutes a day.

IF it is not AC – related, then it must be my setup. I am looking for someone – maybe that's you - to point me in the right direction so I can fix this issue in my system. (But just for the record, nobody has actually come out – in this thread at least - and tested the CPU usage in their systems to prove that it is not AC-related).

Apologies to Zak, I had no intention of hijacking your original post.
