Find a way to decrease the number of entities in entities table

Hello Elgg community members:

I am beginner in developing an Elgg plugin, I notice that all entities are stored in table called elgg_entities ("elgg_"  prefix in my configuration file) in the database, the same thing for the relationships  elgg_entity_relationships (table name in my database) and with time the number of entities  and users increase  , it may cause some performance problems ,is there a technique or another way to decrease the number of entities in elgg_entities table  for example  by distributing entities  in more than one table ,for example table for each subtype of Object type ?

Thank you for your help.
