Since starting in June, SteemReports has been running on a low-end (VPS) server. I finally decided that this was preventing me from doing some interesting work, so I have now upgraded it to use a dedicated server with 32GB RAM. This costs a bit more, but I'm liking the improved performance, particularly on the voting info tools!
More importantly though, it should allow me to do more complex data analysis, make some interesting tools/services and hopefully also migrate from the SQLite database to PostgreSQL over the coming weeks.
