TYPO3 Core

In an instalation with 200000 tt_address records in same sys_folder I experience slow loading:

1. Record list only displays title column, and the first couple records, but takes some seconds to load the page
2. Edit form loads slow because the l10n_parent field fetches all records (even in default language when the field is not shown). The select field seems not to be an ideal choice for this field.
