Hi,
after "Cpanel" to "Site Tools" migration, website is very slow.
An error log:

MySQL server has gone away

Your new server isn't powerful enough, I suggest you move back ASAP.

I'm at Site ground and hate "site tools' but haven't experienced any slow down. Your errors look like something else though.

No surprise here. We recently moved some sites away from SiteGround because of their moving away from the cPanel software, and because there is no reachable customer support, just a bunch of standard help pages. All the warning signs were there to jump ship....
