Having said that, I am not even sure if your observed slow loading is
related to this at all. I _did_ some observations where loading of new
stuff got slower when there were many scalars visible and quicker when
there were no scalars visible. 

Of course, there could be other reasons for slow loading. My anecdotal
experience says I/O related operations are often slower on Windows than
Linux. Virus scanners tend to slow down things (I/O) even more.
