Dennis,  
I have both D5 and D7 installed under WinXP.  
I use both, and prefer D5 for quick programming projects because it loads in a few seconds faster; though for "finished" projects I use D7.
HTH, JohnH

May I why you do the final compilation in D7 instead of D5?
Fewer bugs ( i know D5 has some memory leaks) or better compilation?
Is the resultant exe much bigger if compiled using D7?
thanks

I upgraded from D5 to RAD Studio 2007 within the past year or so. In order 
to do so, I bought a new development machine (Core 2 Duo with 4GB RAM). To 
me, Delphi 2007 slower than D5, but the performance, to me, is acceptable on 
such a machine (your mileage may vary). As I become more and more familiar 
with the new IDE features, I'm quite sure my overall productivity will be 
much higher with D2007-- and that's what really counts, isn't it?

No special reason, except that I believe D7 to be better all around.
Some projects may never see D5.

With Delphi 7 open but doing nothing I see 11 threads in task manager.
Any program that has multiple threads will potentially run faster on a
dual core processor. Delphi 7 is old enough at this point that I think
you'll find it runs plenty fast on modern hardware.

Yes D5 is faster than D7. I have seen that D5 uses some external obj 
files (compiled from TASM) in the RTL. They have been incorporated into 
Delphi 6 as "asm ... end;". The source code looks much cleaner and 
snappier. I think D5 has the best "look and feel".

You really need not be concerned with the loading speed of an IDE.
With modern hardware, software can be written with more features to
increase productivity.  Sure it may take a tiny bit longer to load
initially, but so what?  You live in the IDE all day, and like Frank
said, it's the productivity boost that counts, isn't it?

I develop Delphi 5 plug-ins and some apps for an old commercially sold
software written in Delphi 5.  I write new stand-alone applications in
Delphi 2007.  I often have both running simultaneously.  I don't even
notice that it takes a few seconds longer to load Delphi 2007, but I
sure do like the new features (mentioned elswhere in this group and on
numerous web sites).

The things I notice that slow computers down the most are things like
Outlook and desktop-search engines that constantly index files in the
background.  Don't worry about your development tool!

And if you're worried about the speed of compiled .EXEs?  They're both
practically the same--after all, they're both still Win32 apps, right?
