My session activity table is filling up

[anon666]

I have been getting a lot of errors for possible DDoS attack. I would like to know if it is possible to empty the session activity table, and if that helps to speed up the forum (in addition to taking extreme security measures from cloudflare).

Here is an example of these errors that the control panel shows in large numbers:
