Hi, sorry for the late reply.
We couldn’t test it by having Jetpack on and nothing else as it’s a news site and there’s usually a minimum of 100 people on it at all times which then shoots up to around 500-1000. It would suck if they suddenly saw everything go tits up lol
We’ve since migrated to a new server/host that won’t restrict our resources but at the same time doesn’t give us a way to monitor CPU/RAM usage either, so we’re just going to do what we can until we come up with a better solution.
We’ll certainly check into the site accelerator etc.
Thanks for your help.
