Subject [jira] [Updated] (OAK-5222) Optimize the multiplexing node store
Date Mon, 05 Dec 2016 11:58:59 GMT

     [ https://issues.apache.org/jira/browse/OAK-5222?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tomek Rękawek updated OAK-5222:
-------------------------------
    Description: 
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 -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.
