Re: Help on Query with DATE BETWEEN not performant
Okeh, you've proved it beyond doubt, earticles is the bottloeneck.
The query cache remains disabled??
Are there many of null or invalid or 0000-00-00 dates? -
One at a time, what's performance with ...
- filter on different and/or smaller earticles dateofarticle ranges?
- no date range
- after you drop and recreate primary and dateofarticle indexes?
- after you convert all utf8 cols to utf8mb4?
