Description
While doing some performance analysis we have found that we can reduce object allocations a number of places in the code base.
- In JDBCStoreManager we can create a simple pool(list) of CancelPreparedStatement/CancelStatement.
- BrokerImpl.initializeOperatingSet, use a java.util.IdentityHashMap rather than org.apache.commons.collections.map.IdentityMap.IdentityMap.
Activity
Committed change to use java.util.IdentityHashMap in BrokerImpl.initializeOperatingSet to reduce object allocations to trunk, 2.2.x, and 2.2.1.x
