Hello, I had a similar performance issue working with a very large email set (in the million count). Amongst those, I have crons that run about every minute and email back a report, mostly identical every time with some thousands words. Apparently indexing many times mostly identical emails triggers a pathological behaviour. Moving these email out of my mail directories brought back acceptable performances. We are speaking in the 10,000 to 100,000 files here.
