glusterfs.git/tests/performance, branch v3.6.9 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. performance/open-behind: use anonymous fd for doing fstat and readv 2013-02-20T00:07:21+00:00 Raghavendra Bhat raghavendra@redhat.com 2013-02-19T07:07:04+00:00 f1ce56daf8dff68dc59a7ad4841e428296157011 Change-Id: I61a3c221e0a15736ab6315e2538c03dac27480a5 BUG: 846240 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-on: http://review.gluster.org/4483 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

open-behind: translator to perform open calls in background 2013-02-06T21:16:08+00:00 Anand Avati avati@redhat.com 2013-01-22T00:37:43+00:00 45c04e107c365d29ca9872b5e2d12c932bf43a24 This is functionality peeled out of quick-read into a separate translator.
