hi, i realised i didn't post this beyond IRC, so here are some initial numbers for some performance/benchmarking i did on Gnocchi. http://www.slideshare.net/GordonChung/gnocchi-profiling-21x as a headsup, the data above is using Ceph and with pretty much a default configuration. i'm currently doing more tests to see how it works if you actually start turning some knobs on Ceph (spoiler: it gets better). cheers, -- gord
