             Summary: Optimize the multiplexing node store
                 Key: OAK-5222
                 URL: https://issues.apache.org/jira/browse/OAK-5222
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core
            Reporter: Tomek Rękawek
             Fix For: 1.6


I added support for the multiplexing node store for the oak-run benchmark fixtures. It seems
that the performance in ReadDeepTreeTest is linearly dependent on the mount counts:

{noformat}
Mounts	N
0	729
1	402
2	287
3	209
4	188
5	154
6	133
7	126
8	104
9	100
10	85
20	46
{noformat}
{{N}} - throughput in 60 seconds. Following command was used:
{noformat}
$ java -Dprofile=true -jar target/oak-run-1.6-SNAPSHOT.jar benchmark ReadDeepTreeTest Oak-Multiplexing
--mounts=10
{noformat}

It should be possible to improve this, so we won't have a noticeable performance decrease
for 1000 nodes.
