Limited CPU Usage Bluehost hosting
Bluehost hosting has limits to all of their “unlimited” data claims. Specifically, if you go over 1,000 database table, 3GB total database or 10% CPU usage (if your website is using a lot of CPU) your account will be deleted or suspended
Many users complained about how slow the websites on the reseller accounts are. They consistently ranked as one of the slowest hosting companies. Their average load times are definitely the biggest negative to be find.
Customer support in Bluehost Hosting is pretty slow. Other Bluehost web hosting reviews might not want to tell you this, but every time you reached out to customer service you will have a long wait.
One Set of Default DNS
Bluehost only has one set of DNS: ns1.BlueHost.com, ns2.BlueHost.com.
If you have an existing site, Bluehost is going to charge you a $150 transfer fee for migration which some of other hosting companies will do it for free. They also limit you to five sites and 20 email accounts.
Bluehost only offers Linux servers. Not a huge deal for most users. For those running Windows-specific features, though, it could put a damper on your web hosting plans with BlueHost.
Although Bluehost claim 99.9% uptime, some people experienced frequent downtime.
