This is an ongoing issue with qtbittorrent consuming all of memory

[Christophe Dumez (hydr0g3n)]

I'm not good with that sort of thing and I have to admit that this sort of thing is handled by libtorrent-rasterbar, and not qBittorrent itself.

My guess would be that default settings are not appropriate for so many torrents. The question is, what settings should be tweaked in order to consume less memory when having so many torrents.

in qBittorrent v2.1.0beta1, the user can already tweak disk cache size from program preferences. Would that be enough or is there other settings I should consider?

Libtorrent settings are explained here:

There are two options in session-settings: disk_io_write_mode and disk_io_read_mode, setting them to disable_os_cache would solve this problem. It would be nice to have this option in Advanced Options of qBittorent.
