show alot of queries that was'nt using any index, can these queries
cause some kind of occasional lock up?
Is there a fas

Performing an index only query such as SELECT COUNT(*) is extremely

Hi MySQL ,
I have made a test database for performance testing
and my InnoDb tablespace grew from 1Gig to 8 Gig...
After I dropped that test database, the tablespace
stayed to the same size. How can I "resize" it to its
original size?

You just started the server. If you want to run it as
a service (I assume you have Windows NT or 2000), use
the --install option.
Now, you could open another command prompt window and
start mysql with, for example:
mysql --user=someguy --password=secret
Hope this helps.
