i disable system cache in fbconfig

normal option like in flamerobin all unchecked (garbage collector work, and disabled use all space if you think about this options)

also i see that db size not grow under sweep proces – then i suppose free space was enough for storing delete info – (but could be stored on the free unused pages also i do not know)

l have ~4 indexes per table – but tables have not any constraints like pk, uk – if this is important info
and some indexes have depth 3, all others have depth 2 – if this is important info

I can prepare some db for exclusive fb-team test if wishes – this take some time but is possible
