Influence of amount element range indexes on memory consumption

I am interested, how amount element range indexes influence on system performance? I mean those indexes which are used very rarely. Maybe I should remove they, or they do not affect on RAM memory consumption?

All range indexes are memory-mapped. The OS may be able to page them out if they are not being used, but either way they should not affect performance as long as there is sufficient memory space available.

You can see exactly how much memory your forests use on the forest-status page, in the admin UI. Or you can call xdmp:forest-status() to get the same information. It is less easy to find out how much space any given index uses, but sometimes possible.
