[Archivesspace_Users_Group] Solr review

[Tom Hanstra]

Thanks, Brian.

Some more questions, assuming that I've gotten the configuration and cores
set up correctly.

- Memory: In my Archivesspace 2.8.1 instance, Solr and ArchivesSpace are
sharing the same Java memory (as far as I can tell). When we split them up,
are there suggested amounts of memory for each?  Do I need more memory
given to Java in order to address having these separated out?

I'm trying a soft reindex to see if my Solr and ArchivesSpace are not in
sync, but one thing I notice is that memory for Solr itself, because it is
external, is much lower than my production server. What do others use
memory and thread wise?

It seems to me that I'm resource bound somewhere, but I've been unable to
track down where so far. It seems like soft indexing should be pretty
speedy, since Solr records are already in place, but it is going quite
slowly so far.

- Other configuration settings
Might there be other Solr configuration settings which need to be tweaked
to speed up processing? There are a lot more values displayed in 8.11.1
that seem like they could be changed.

Tom
