There already is a test to verify the mempool sharding works, in the sense that it uses at least half of the variables available to count the number of allocated objects and their total size. This new test verifies that, with sharding, object counting is at least twice faster than without sharding. It also collects cacheline contention data with the perf c2c tool. The manual analysis of this data shows the optimization gain is indeed related to cacheline contention. Fixes: https://tracker.ceph.com/issues/49896 Signed-off-by: Loïc Dachary <loic@dachary.org> |

qa/standalone
=============
These scripts run standalone clusters, but not in a normal way. They make
use of functions ceph-helpers.sh to quickly start/stop daemons against
toy clusters in a single directory.
They are normally run via teuthology based on qa/suites/rados/standalone/*.yaml.
You can run them in a git checkout + build directory as well:
* The qa/run-standalone.sh will run all of them in sequence. This is slow
since there is no parallelism.
* You can run individual script(s) by specifying the basename or path below
qa/standalone as arguments to qa/run-standalone.sh.
../qa/run-standalone.sh misc.sh osd/osd-dup.sh
* Add support for specifying arguments to selected tests by simply adding
list of tests to each argument.
../qa/run-standalone.sh "test-ceph-helpers.sh test_get_last_scrub_stamp"
