But I've been using pretty *anything over LUKS/LVM for years, and I've never notice it cause any (noticeable to the point of becoming annoying) system slowdown, whatever tasks I may have processed in such setups (including servers, big databases, compilations, NAS, etc...) So I doubt that the encryption is involved here... At least not very heavily involved. But I may ask my son if he volunteers to test the same on his unencrypted BTRFS netbook... > Besides that, as Hugo told you, you can disable btrfs cow on the database files, > but given my experiences I wouldn't put too much hope into that part. As far as I understood, this option won't work unless I have a 3.7+ kernel... BTW, what is the effect of "nocow" with respect to snapshots ? I would assume that then, snapshots contain the current data ?
