limit memory usage

[milahu]

the current way to limit memory usage
seems to be to reduce --max-blocking-threads 8
to something like 2

but then checking torrents is slow
as only 2 torrents are checked in parallel

so --max-blocking-threads
seems to limit both cpu and ram

im looking for an option to limit only ram

edit:

but then checking torrents is slow

also with
--max-blocking-threads 8 and
--worker-threads 8
only 2 torrents are checked in parallel

but this could also be
a resource limit of the machine
(cpu load is 16/24)
