stephen mallette commented on TINKERPOP-1676:
---------------------------------------------
Already pushed this little change to make better use of memory:
https://github.com/apache/tinkerpop/commit/7ea38751871f6eddd4c4bcfe8ac82300a08f5a7d
It basically reads vertices/edges from a stream in TinkerGraph serialization
(when passing subgraphs back from Gremlin Server) rather than building up a big
List of vertices/edges in memory to later iterate through. That change seemed
to reduce the number and frequency of GC operations.
> Improve GraphSON Performance

> Key: TINKERPOP-1676
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1676
> Project: TinkerPop
> Issue Type: Improvement
> Components: io
> Affects Versions: 3.2.4
> Reporter: stephen mallette
> Assignee: stephen mallette
>
> Not sure what will happen here. Just wanted an issue where I could experiment
> a bit with and gather feedback from others for collaboration in case others
> had ideas. Right now, GraphSON reads are considerably slower than Gryo and
> writes appear to be faster, so the focus will be on how to get reads more in
> line with what Gryo can do.
