This will have a serious impact based on that kind of database. A good caching plug-in like WP Rocket should help with the overheads and speed things up. If you have server side caching like memcached or lighspeed make sure you are utilising it. Source: about 1 year ago

One of the most beloved WordPress caching plugins is WP Rocket. They’ve managed to take something complex and make it extremely easy, yet still powerful and configurable. They have also made it easy to integrate with a CDN in just a few clicks. - Source: dev.to / over 1 year ago
