Subject: CM versions.

I have used all the CM versions since 6000. But my favourite one was CM9000.
What do you guys think?
There is something about CM10 I just don't like. I can't seem to understand what
is it. It's probably the new look. Also the Database import (from PGN) function
of CM9000 was much much (almost 10times) faster than CM10.
I was trying to import a 1 million PGN games database into CM10 format. After
leaving it working on it for more than 20 hours on a P4 2.66 it was barely 50%
done. On comparison CM9 is crunching on the database, like it's on steroid.

I never really fiddled with CM database features. I am looking for a Database
that's extremely fast while doing positional search, at the same time the
database is not too bloated. Scid is OK is this regard. It's kinda slow in a
position search. And I hate the fact that it loads the whole database in the
memory every time you open it; try opening a 4million game database in SCID when
you have 750mb memory. PosBase is amazingingly fast but the database format is
hugely bloated, even more than PGN format. And there seems to be a serious bug
in the program.

CM9 is the winner so far in terms of features that I am looking for. It also
seems to avoid importing games that's already in the database. I am not sure if
it's true. If it is the case. It would be an awesome feature.
