The surprise is that some things run slower. One thing that is
particularly
noticeable often occurs when entering text into a web page input area.
With
each keystroke, I can see the caret moving across the white background,
but
no characters appear. Sometimes I'll type in five or six keystrokes
before
it gets around to painting the characters behind the cursor. Another
occurs
with crossword puzzles displayed in Flash objects, such as the one in the
daily L.A. Times. For these crossword puzzles, first you have to poke a
puzzle-selection button; then it pops up a dialog with a choice of
"regular"
or "master" skill level. The pop-up used to display instantly; now
there's
a delay of about three seconds.

Why would some things run slower after an increase in RAM??

It's understandable after adding the ram to think it has something to do
with this behavior, but it seems unlikely. Try running the Windows
Experience Index again - are all the scores reasonable? Since you mentioned
"flash" do you have the latest version? Try the crossword puzzles in a
different browser to see if that makes a difference. Do you see the typing
slowdown in other applications or only the browser? If it's only in the
browser that would suggest a slow internet connection. You can run a
performance test on your internet connection at dslreports.com.
