Forum running slow

Could be the server is below DDoS...
Many forums are in same state, also our:

 

In my case, massive guest access to the pages, till 150000 for day, continuously increases the session table and session keys in the server database,

which slows down more and more every day, paralyzing the forum.

 

At the moment, the only solution I have is to periodically clean up the two tables, but this also disconnects all connected users...

 

I hope this is not the problem in this forum.

This was to an ICS web server, and I contained the problem by adding geographic blocking using IP addresses and ASN checking, so requests are terminated before being connected.
