Although I don’t believe that the size of the database matters much in today’s hosting environments, it might indeed be wise to do some cleanups in your situation, on the setting page, I suggest you remove all auto translations older than 14 days, don’t worry much if you lose any auto translation being used as those should be rebuilt anyhow.
Ingawa mimi si kuamini kwamba ukubwa wa database mambo mengi katika mazingira ya leo mwenyeji, inaweza kuwa na hekima ya kweli ya kufanya cleanups baadhi katika hali yako ya, katika ukurasa wa mazingira, Mimi mapendekezo ya kuondoa tafsiri auto wote wakubwa zaidi ya 14 siku, usijali sana kama kupoteza tafsiri yoyote auto kutumika kama wale lazima upya anyhow.
