---------------------------------
Summary: Reduce PerfLogger isDebugEnabled overhead
Key: OAK-3361
URL: https://issues.apache.org/jira/browse/OAK-3361
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Affects Versions: 1.3.4
Reporter: Joel Richard
If a node is cached, 1/4 of the time which is used to call
DocumentNodeStore.getNode is spent in PerfLogger.start and PerfLogger.end just
for checking whether or not debug logging is enabled (this is likely much less
if no TurboFilters are used).
To reduce the overhead of the PerfLogger, it should not check if debug is
enabled in end() if start is below 0 anyway. Moreover, it would help to check
only every second if debug is really enabled.
