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.

If I upgrade to D7 or even newer version, will the IDE and compiler runs
considerably slower?
I know new versions has larger packages loaded in memory. If I unload all
unnecessary, infrequently used packages in the IDE, will it consume similar
amount of memory?
My concern is: I got a new Duo Core computer, if I upgrade to newer version
of Delphi, will it slow it back to the old speed of D5 on single core
computer and defeats my purpose of getting a Duo Core?
Thanks in advance.

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".

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?
