Hello,

I would like to know what's happening when we execute this command: db_start
and db_warm.

This question comes from the following situation: We are trying to do a
benchmark and here is the procedure:

1. db_start
2. db_warm
3. execute the query: select count(*) .... -> we get the execution time (for
example 4 min.)
4. execute a second time the same query: 56 sec.
5. db_stop
6. db_warm
7. execute the query: select count(*) .... -> we get the execution time 56
sec (again!)

I don't know why after a shutdown of the database(db_stop) the query doesn't
take the same time than the first time we executed the query??????????????

What does the database during a db_start and b_warm?????
Thanks,
S�bastien
