------------------------------------
Summary: Speedup creation of JCR session
Key: OAK-2773
URL: https://issues.apache.org/jira/browse/OAK-2773
Project: Jackrabbit Oak
Issue Type: Wish
Components: core
Affects Versions: 1.2, 1.0.12
Reporter: Przemo Pakulski
JCR sessions used to be lightweight objects and chip to create in
Jackrabbit2/CRX.
I noticed that in Oak creation of session is significantly more expensive. On
my environment creating Oak sessions is ~10 times slower than in crx2.
The most of the time is spent in PrincipalProviderImpl class which executes
many queries.
Possible solutions are:
* introduce MembershipCache as it was in Jackrabbit2
* speed up the queries, actually the queries itself are pretty fast,
calculation of execution plans is heavy and adds much overhead
* both
