Anybody have any paging performance issues on Windows? While I am moving
the camera through the database, I get hitches in frame rate. The frame
rate will drop from 100 to about 5 Hz, and stay at 5 Hz for multiple
seconds.
It appears as though the paging thread is taking over the processor
completely when the performance goes bad.
I did try the same database on Linux, and it only has an occasional
split-second hitch in performance. This is how I believe OsgSceneHandler is
coded. I mean it doesn't give the DatabasePager any time if there is no
time left. Since on Windows, the behaviour doesn't match this, I am
assuming there is a problem with the Visual Studio implementation of
OpenThreads. Has anybody else done some investigation on this?
I know some will blame Windows. But, I'm quite positive the OS cannot be
blamed for multiple second hitches (3-10 seconds of hitches).
Thanks for any help you can give!
