I'd not thought of that. In my experience speed is not what it was. I
buy the latest hardware without any idea of how much faster it is.
Feckless programmers then throw away any speed gains with poor code.
We've now had the "Spectre" event which has supposedly slowed things down.
I used to benchmark Ovation Pro by seeing how long it would take to
format a large text file. But on Windows probably the slowest thing is
moving a JPEG around - because I never got around to optimising JPEG
rendering.
32 bits lets you address 4GB of memory. Documents have 32 bit values in
them. So allowing documents to go above 4GB would mean a new format.
Although that could be a simple generalisation of the current format,
would one really do that.
The idea of OP docs is that they can be "block loaded", they're an image
of memory. Do you really want to load more than 4GB in one go, on the
grounds that it is fast.
Many of my assumptions are based on how it was in 1992.
