- I'm wondering if REST works differently, or just doesn't log these sessions?
- I wonder if they are measurable via JMX MBeans?
- I came across some interesting PostgreSQL tuning advice for SSDs: https://amplitude.engineering/how-a-single-postgresql-config-change-improved-slow-query-performance-by-50x-85593b8991b0
- Apparently setting `random_page_cost` to 1 is "common" advice for systems running PostgreSQL on SSD (the default is 4)
- So I deployed this on DSpace Test and will check the Munin PostgreSQL graphs in a few days to see if anything changes
