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?
