slow db query meta key

Why It Shows Up

The scan found query arguments such as broad meta queries, tax queries, or unindexed lookups that commonly become expensive as content grows.

Why It Matters

A query that feels fine on a small test site can become a production bottleneck on large stores, membership sites, or publishers.

How to Fix

• Avoid broad `meta_query`, `tax_query`, and unindexed searches on front-end requests when possible.
• Cache expensive results with transients, object cache, or precomputed data.
• Add narrower constraints, pagination, and indexes when custom tables are appropriate.
