The number of tables can become a problem for your system tables when not using LMT. Several system tables get fragmented and can only be reorganized by re-creating the database. Therefore I advise to use LMT or edit the sql.bsq file before creating the database.
PS. Editing the sql.bsq file should only be done by experienced people and can lead to unsupported environments. Therefore I don't give the things that should be changed.
