So I got several Sendy licenses, and was running them all on different Linode's. This week I decided to move everything to a single Linode and say "screw it to slow speeds" which decreased my spending from $450~ a month to $80 a month.
Well, I wasn't watching myself and left everything default PHP7.4 for the move, nor did I increase any PHP settings (memory). Since sticking with PHP7.4 my sending speed as not only stabilized on all my installs, but it's actually increased.
Is anyone else experiencing this?
