The decision to force a re-index was taken on the basis of testing that it was pretty fast, triggered at first startup and only a few seconds in duration. It certainly wasn't meant to be a 5-hour offline operation, even for massive databases. If anyone in this thread is able to put the upgrade under a perf and produce a flame graph, that would be an awesome start to understanding what has gone wrong here. http://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html#Instructions I'm assuming this is on TDB and not LMDB?
