SpeedUp new woocommerce site backend

Job ID: 33459353

Budget: €30 – €250 EUR

I'm creating a new WooCoomerce site on a new dedicated server with no other sites on it.
I find that duplicating, moving to the trash, and emptying the trash is slow when compared to demo.woocommerce-b2b.com .
As an example, on my server, it takes about 30s to empty the trash with 14 products, while on the demo site it's almost immediate.

Note: These products have variations.

Your mission is to make the site's backend as fast (or almost as fast) as in this site:
https://demo.woocommerce-b2b.com/wp-admin

My datacenter dedicated server specs are:
AMD Ryzen™ 5 3600
64GB RAM
2x 512GB SSD
CentOS 7.9 + Cpanel

Maybe something needs to be optimized in the server's mysql, php settings or in WordPress itself.
I'm running out of ideas and I need an expert to help me out.
