---------------------------------
Summary: Optimize UpdateManyChildNodesTest
Key: OAK-922
URL: https://issues.apache.org/jira/browse/OAK-922
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Jukka Zitting
Assignee: Jukka Zitting
The {{UpdateManyChildNodesTest}} benchmark looks pretty bad for Oak:
{noformat}
# UpdateManyChildNodesTest min 10% 50% 90% max N
Jackrabbit 12 14 17 36 486 1263
Oak-Tar 380 458 483 548 1079 61
{noformat}
The main culprits are an O(n^2) algorithm in {{ChildOrderDiff}}, an O\(n)
comparison in {{AbstractPropertyState.equals()}} and some missing SegmentMK
optimizations.
