How to build a efficient Load Balance?
the reason is the very heavy database MYSQL...
a website with 30,000 articles.
I thought about separating the database, creating a file. But I don't know if it's possible with the same URL address.
My intention is to make a Load Balance that is easy to implement and performs well.
Linux Ubuntu Server 20.04
virtualmin
Nginx
PHP 7.4
mysql
WordPress
I'm having trouble finding updated information about Load Balance. Although the questions clear some doubts, but they are out of date and many unanswered... Look: [link][1] [1]: https://stackoverflow.com/search?tab=relevance&q=%5Bload-balancing%5D%20Wordpress
I am not a WordPress expert, but with my basic knowledge about WordPress (I have my personal blog in WordPress), I can put an answer together that might enlighten you.

To analyze your website, there are some online tooling like:
or
Both sites offer some suggestions on how to improve your performance.
I would also parallel to that also read some articles about How to optimize your WordPress (one example).
