Post-Meeting Summary

Today was all about performance as we had demos of both Solr's 'benchmark' module, and the solr-bench repository maintained by FullStory.  Demos and discussion of those took up most of the hour.  We started discussing when each should be used and the overlap between the two but were cut off prematurely by the meeting ending and kicking everyone.  ('Free Tier' Google Meet has a 1-hr maximum that I'll account for next time.)
