Marcel Reutegger resolved JCR-689. ---------------------------------- Resolution: Fixed Committed second patch in revision: 518986 > Minimize calls to PersistenceManager > ------------------------------------ > > Key: JCR-689 > URL: https://issues.apache.org/jira/browse/JCR-689 > Project: Jackrabbit > Issue Type: Improvement > Components: core > Affects Versions: 0.9, 1.0, 1.0.1, 1.1, 1.1.1 > Reporter: Marcel Reutegger > Priority: Minor > Fix For: 1.3 > > Attachments: JCR-689-r492483.patch, NodeImpl-485720.patch > > > In some situations the PersistenceManager is called even though it is not > necessary. > E.g. when new items are created the method NodeImpl.getOrCreateProperty() > will always check if there is an already existing property state. If the node > is new the call will always go down the full item state stack and ask the > PersistenceManager if it knows the property id. This is unnessessary because > there will never exist properties in the persistence manager for a new node > that has not been saved yet. > I propose to add a check to the method to see if the node is new and does > not yet have a property with the given name. In that case the property can be > created without further checks. > With the patch applied the time to transiently create 1000 nodes with 4 > properties each drops from 1485 ms to 422 ms. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
