Bluehost CPU quota
The CPU quota is surrounded by a lot of mystery, speculations and rumours. Recently, Alligosh, Bluehost’s principal systems administrator dropped into the bluehost forum and gave an exact definition of what constitutes the CPU limits.
The Bluehost CPU quota defined:
The CPU quota is calculated using a set number of runtime CPU seconds over a set number of realtime seconds.
With us, if you use more than 40 CPU seconds over a 60 realtime second period, the cpu quota system will suspend the website until the average over the last three minutes is below 40 CPU seconds. The three minute average is calculated every 15 seconds for the previous three minutes. As soon as your average is below the 40 CPU seconds, you will be unsuspended.
Also, processes are not terminated for going over the quota, as we don’t like killing half done processes. After the process finishes, it’s entire CPU usage is added into the last minute of processes.
If you have 200 processes in a minute that each use .5 CPU seconds, it will get you suspended. If those same processes take two minutes, you won’t get suspended.
Since the last sentence didn’t make any sense Alligosh later clarified that he meant to say .4 CPU seconds which makes sense again.

BH also has a high CPU plan for $19.95 a month where you’ll get 90 CPU secs per minute.

Good point – I forgot to mention the possibility of an upgrade.

I just switched to higher cpu server. Guess what? It’s not better
Damn these CPU errors are pissing me off!
Bluehost please make a move and solve this out before you lose your customers!

Hi Uros,
according to a tool I used you’re getting around 100k visitors to your blog. Not sure if it’s a wordpress blog but blog scripts have pretty slow queries and that many visitors will be very CPU intensive. Last time I checked your blog was up so I hope you overcame this CPU problems. Otherwise I would suggest you go with a cheap VPS plan or the Hostgator Reseller plan.
I took a look at your site and it has a lot of potential for monetization, so it will pay for your hosting. I would suggest Google or a CPM program. If you want details email me at hostingblog [at] cheap-webhosting.in

Hello Hostmaster,
Last time I’ve contacted BH support they said no matter how much I optimize the site BH shared account cannot handle so much traffic. They recommend to get semi-dedicated or dedicated server. I think VPS might be good enough for now. I will check links you posted here.
Do you also have msn? Would be much easier to talk.
Best,
Uros

Hey Uros,
I sent you an email and you can add me to your MSN with that email. I sent it to the address that you supplied when you commented.
