Then, in recent days, I tested HawkHost shared account recommended somewhere here on Xenforo forums. Their shared account is based on Cloud Linux which works in similar way to VPS in terms of resource limitation. I can access resource usage stats. I run it on the limit, but actually my forum is much faster than it was on Host1Plus VPS where I was running at probably 20% of my resources. Here is my HawkHost last 24 hours usage report:
I recommend it for forums with less than 100 online users. cPanel based, SSD drives - plenty fast. And data centers also in Europe.
They said if I find resources too limiting I may upgrade my account to Semi-Dedicated which has twice the power. But so far I am absolutely fine on regular shared account.
Big thumbs up for HawkHost.
