Ted Wilmes commented on TINKERPOP-1287:
---------------------------------------
As part of starting to look into this, I profiled various stages of a
{{g.V().count()}} against a subset of friendster data. Profiles are attached,
but I may have found another bit of low hanging fruit. It looks like the
{{String.intern()}} calls made during {{StarElement}} and {{StarProperty}}
construction are taking a good bit of time. I did a quick test and saw runtime
improvements but more thorough testing needs to be done. If that looks good, I
may include the removal of interning in my PR for review. I checked to see if
I could find any String {{==}} checks that would have been benefitting from the
interning but did not see any but very well could have missed them, or another
specific reason to intern. I will also check and see what effects this has on
memory usage.
> StarGraph has an overdose of Stream usage.

> {{StarGraph}} is loaded with {{Stream}}-usage. Gutting streams from
> TinkerGraph made it much faster. It would be good if we did the same thing
> for {{StarGraph}}.
> This can go into tp31/ and upmerge to master/.
