- To me it seams that Designer has become faster with large images, and
- there is also a theoretical explanation for it (se below).

-
- I agree with most of what Richard Plourde says. But just to make some
- of his point a bit clearer:
-
- (1) 32-bit apps have separate addresses. That means that if the app
- crashes, it usually won't crash the system,although this also can
- happen since they also are part of the common System VM, that is
- shared by Windows code and 16-bit apps. (16-bit apps share addresses.)
-
- (2) 32-bit apps are pre-empetively multitasked, as opposed to the
- corporate multitasking with 16-bit apps (which usally don't work very
- well). This means you can very well download a 3MB file in the
- background while spell checking and printing (impossible with 16-bit
- apps).
-
- (3) More and more of the 32-bit apps are multithreaded. Take Word 95
- as an example. One thread spins off for background printing, another
- one is used for one-the-fly spell checking, the third is for the rest
- of the program. These threads are pre-emptively multitasked. The gain:
- more responsive apps.
-
- (4) The segmented 64K limit is removed. This is especially important
- for huge databases and graphic programs (flat addressing).
-
- Now some of this is still theory, some of it is already in place.
- Programmers need some time to learn how to program good 32-bits apps.
- It took long time with OS/2. For Win 95 I expect most of the 32-bit
- apps to be more or less plain ports, giving little advantage.
-
- Generally, 16-bit apps are still faster, especially when loading.
- Every benchmark I've seen proves this.
-
- If all you want is task-switching WfW is still the better choice, if
- speed is the main issue. But for multitasking you're better of with
- Win 95 and 32-bit apps.
