I recently faced a frustrating WordPress issue where my site became very slow after the latest core update. After troubleshooting, I found a few key fixes that helped: clearing all cache, upgrading to PHP 8.1, disabling WP Cron, and using Query Monitor to identify a heavy plugin. These steps really improved my site speed. I also wrote a detailed guide on my blog if anyone else is facing a slow WordPress site after an update.
