Hi Folks, Per yesterday's Ceph performance call, we've pushed 2 wip branches for review and feedback to https://github.com/linuxbox2/linuxbox-ceph.git . 1. xio-v084-inline reorganizes ceph::buffer as a namespace, and (nearly) all of buffer::hash, buffer::ptr and buffer::list as inline 2. xio-v084-inline-flat restores some raw encapsulation lost in the prior change, then refactors buffer::raw to remove virtual methods We've made some effort to measure the impact of the changes, but don't have reliable data yet. (It's possible that our initial impression of improvement from the inlining change was not accurate, but more likely we need better workload tests.) In addition, we've been working on an experiment to refactor buffer::ptr and buffer::raw to use boost::intrusive::list, to unify the interfaces of the two types to permit interning buffer::raw directly on the containing list when there is no sharing, and a slab allocator for both types. We plan to push a wip branch with these changes to when they've stabilized a bit more and/or we have real perf numbers.
