Comment 2 for bug 1185463

When access to forms with Forms/Subforms combination (Parent-Child Relationship) the parent record display fine but the subform data display takes long time (4 secs before update to 40 secs with the upgrade)

I changed from 4.0.2 (official repository) to downlodable 4.0.3 and turn worst.
I changed ODBC and drivers from MySQL and the same result.
I reinstall MySQL server to avoid DB-Tables perfomance issues.
I checked CPU usage and almost takes 100% when navigated thru records

I had to downgrade to LO 3.6.6 version and works as expected (as long as Ubuntu 12.04).

At present time I use:

Ubuntu release 13.04
MySQL 5.5.31
