The FileStore's leveldb currently uses libleveldb's defaults for cache and write buffer size, which are both 4 MB. Increase the cache size to 128MB and the write buffer to 8MB. Tested-by: Dmitry Smirnov <onlyjob@member.fsf.org> Signed-off-by: Sage Weil <sage@inktank.com>

* The default leveldb cache size for the ceph-osd daemon has been
|
|
increased from 4 MB to 128 MB. This will increase the memory
|
|
footprint of that process but tends to increase performance of omap
|
|
(key/value) objects (used for CephFS and the radosgw). If memory in your
|
|
deployment is tight, you can preserve the old behavio by adding::
|
|
|
|
leveldb write buffer size = 0
|
|
leveldb cache size = 0
|
|
|
|
to your ceph.conf to get back the (leveldb) defaults.
