09:17 PM Ceph Revision 1f1c6f39 (ceph): osd/PGPool::update: optimize with subset_of
Replace expensive inverval_set intersection_of and operator==
calls with a single subset_of call. I borrowed this ide...
09:12 PM Ceph Revision e9ee4dd9 (ceph): PGPool::update: optimize removed_snaps comparison when possible
In self/unmanaged snaps mode, optimize removed_snaps comparison
for cases where removed_snaps has not changed. This e...
09:11 PM Ceph Revision 70bb615b (ceph): PGPool::update: avoid expensive union_of
Achieve the same result using a swap (constant complexity),
and an assignment (linear complexity).
Signed-off-by: Za...
09:10 PM Ceph Revision d68cff3d (ceph): PGPool::update: optimize with interval_set.swap

performs better than the lower_bound method, for set
size ratios ...
06:34 PM Ceph Revision 4aefab03 (ceph): interval_set: optimize intersection_of
Iterate over all elements of the smaller set, and use find_inc to
locate elements from the larger set in logarithmic ...
