Re: Help on Query with DATE BETWEEN not performant
Yes the fast 2nd run is due to the cache, which is removed in 8.0 so you may as well disable it now.
I'd expect MySQL to use the earticles.dateofarticle index, did you try Force Index on that key? It shouldn't be necessary, but if that doesn't work consider replacing that index with (dateofarticle,id).
I'd also experiment with fewer buffer pool instances.
