-----------------------------------
Summary: Increase default JVM heap setting.
Key: JENA-1832
URL: https://issues.apache.org/jira/browse/JENA-1832
Project: Apache Jena
Issue Type: Improvement
Components: Fuseki
Affects Versions: Jena 3.14.0
Reporter: Andy Seaborne
Assignee: Andy Seaborne
Fix For: Jena 3.15.0
The script default is {{-Xmx1200M}} which is quite small these days (we can
ignore 32-bit setups in choosing defaults).
We could simply leave it to the JVM default (25% of RAM).
Considerations:
* we don't want to squeeze out memory mapped files.
* 25% is a lot on larger servers if shared.
For TDB1/TDB2, a key use of memory in heap is the node table cache.
Other than that, it is intermediate query processing space.
