Lower memory overhead in Infinispan 5.3.0.Final
Infinispan users worried about memory consumption should upgrade to Infinispan 5.3.0.Final as soon as possible, because as part of the work we’ve done to support storing byte arrays without wrappers, and the development of the interoperability mode, we’ve been working to reduce Infinispan’s memory overhead.
To measure overhead, we’ve used Martin Gencur’s excellent memory consumption tests. The results for entries with 512 bytes are:
Infinispan memory overhead, used in library mode: Infinispan 5.2.0.Final: ~151 bytes Infinispan 5.3.0.Final: ~135 bytes Memory consumption reduction: ~12%
Infinispan memory overhead, for the Hot Rod server: Infinispan 5.2.0.Final: ~174 bytes Infinispan 5.3.0.Final: ~151 bytes Memory consumption reduction: ~15%
Infinispan memory overhead, for the REST server: Infinispan 5.2.0.Final: ~208 bytes Infinispan 5.3.0.Final: ~172 bytes Memory consumption reduction: ~21%
Infinispan memory overhead, for the Memcached server:
Infinispan 5.2.0.Final: ~184 bytes
Infinispan 5.3.0.Final: ~180 bytes Memory consumption reduction: ~2%
This is great news for the Infinispan community but our effort doesn’t end here. We’ll be working on further improvements in next releases to bring down cost even further.
