Re: DBC mixed with Free tables performance



My tables are on a network drive. I am currently working with test data so
I am the only one accessing it.

A table in a DBC vs a free table should have no impact on performance.
Where are your tables located? Are they on a network share or local? Are
other people or applications currently accessing them?

I am using VFP9.

I am in the process of creating a database container for my free tables.
I have quite a few tables and would like to implement this
incrementally.

My question is, are there any performance problems with mixing tables in
a dbc with free tables?

I have a query that uses 4 tables to get some data. When running it
against my free tables it runs in under a second. When I run the query
against the same 4 tables only with two of them now added to the
database container the query takes over 30 seconds. I am not sure why
this is happening. SYS(3054) reports the same optimization for both
queries.

Please help...
