I'm sorry to say that the 2006 R3 is yet another steep step downhill
in graphics speed. Significantly slower even than 2005 - 2006R2,
which it itself was a significant step down from 5.5. At least 50%
slower on OSX PPC, al lot worse on OSX Rosetta / IntelMac and worst
of all on WIndows where I have seen slowdowns by a factor of five to
one.
I was extremely disappointed as the only thing I really needed was
Universal Binary and performance back to at least the level of the
5.5. I would not mind having the IDE performance, the compiling
speed, and the file sized of the 5.5 back also, but I guess I could
live with, reluctantly, if it just delivered the right performance
in the compiled program. I simply must have the speed it used to
have, at least, for my use or RB

I have been waiting for the latest release rb6 to test out my show
stopper for not migrating any of my clients major application to
rb6 from rb5.
The simple problem is speed of drawing anything on a window. I have
followed various threads about the complexity of redrawing canvas's
with complex components but this is much simpler than that.
I build a window and create a control array of 32 statictext items.
Add a pushbutton that flips the value in each of the statictexts
from AAAAAAA+Str(n) to BBBBBB+str(n)
Compile the program on a mac for win. Load the .exe on to a pentium
4 @3ghz
Run the program
Compiling with rb5.5.5 - instant redraw of the text
Compiling with rb6 r3 - very slow visible serial updating of each
text item (Hard to estimate but about 3 times as long)
In my key application of a Point of sale system the screen has to
be redrawn many times.
Currently the text sits inside round rectangle and is grouped with
it - in rb6 this is embarassing, first the rectangle is drawn 50
times down the screen then the text is overlaid. (this is a fast
food application).
In RB5.5.5 this is just about faster than the eye can see - no
flicker no idea of a serial update of each of 50 menu keys
But back to the simple test.
Can anyone confirm that refreshing and drawing of any screen on a
Win machine in factors of speed slower between 5.5.5 and rb6 r3.
Does the Window compiler work any better?? (he said in hope!)
