1. Our WordPress and WooCommerce multisite is running slowly at times, the pages on the site and in the admin area take far too long to load. 2. We need website speed optimisation. 3. We need to pinpoint the source of the backend slow down and fix it. 4. We need database speed optimisation, not just doing a simple clean, we've done that, I'm looking for someone who can optimise say the top 30 queries consuming the most database time.
