The setting you're looking for is bluefs_buffered_io. This is very much a YMMV setting, so it's best to test with both modes, but I usually recommend turning it off for all but omap-intensive workloads (e.g. RGW index) ...
We're not using RGW, only RBD. Currently I find it hard to prevent Linux from swapping at least a little no matter what vm settings I use. Thanks. -- - Brian
