My WordPress Site is extremely slow!

Hi support team,

I have a news website with currently about 25000 posts. The site is extremely slow and I don’t know what else I can do to improve the performance.

Surely this could be a database problem. I don’t know if WordPress has speed issues when the DB is continuously growing.

I hope someone has a solution or advice for me.

Thank you very much in advance

Best regards
