VPS CPU utilisation policy

This policy is an extension of our terms of service located here. We want to ensure you have access to the resources you need, as you need them. We recognise that sometimes there is a need to use more CPU processing power on occasions and we want to make sure you can use those resources when required without setting the base CPU utilisation limit too low. This means that at those critical times when you need a little more CPU horsepower, you can get it.
To ensure the stability of our service into the future we are establishing an automated CPU utilisation policy. This means that our systems will automatically review how much CPU you are utilising per core over a given period; and if necessary, curtail your VPSs request for CPU resource if it is deemed to have exceeded the criterion defined by this policy. Please see the CPU policy in the table below.
This policy is applied universally across all VPSs unless we have specifically agreed an exception as part of a bespoke set of requirements and commercial agreement. If you wish to discuss your bespoke requirements, please raise a support ticket into the Sales Department.

Band Average CPU utilisation on host server (per VPS core) Average measurement period (minutes) VPS CPU throttle penalty (per VPS core) VPS CPU throttle duration (hours)
A 90-100% 15 20% 3
B 60-90% 15 25% 3
C 40-60% 15 30% 3

If on average over a 15-minute period you use less than 40% of the host CPU per VPS core then you will never need to worry about throttling and will be able to use 100% of the available CPU for periods where you need extra performance for short bursts. We find that this policy strikes a reasonable balance between performance and stability.

Question: How do I know when my VPS is being throttled?

We’re working on making this more transparent but your VPS is likely to show steal time within “top” when your CPU bandwidth is being constrained on the host machine. Contrary to popular belief, steal doesn’t always mean the host is overprovisioned, it can also mean deliberate throttling (such as in the case of a policy such as this) is being imposed due to over-utilisation of CPU bandwidth.

Question: Do other hosts impose these types of limits?

Other hosts may not make it clear that they have a policy for this but they usually do. Unless you are specifically purchasing dedicated CPUs for your VPS (and paying for the benefit of this) you will be subject to a fair use policy by other hosts and usually their policies in this area are vague and leave you wondering how much (or little) CPU you can actually consume and for what duration. Most other hosts have to manually react if users are seen to be abusing CPU resources to the detriment of other users, whereas our system is completely automated and driven by the policy detailed in the table above. This means that if other users are abusing CPU resource on the host machine, you don’t need to wait for us to do something about it manually as our automated system will handle this and restore stability. This means that the rules are clear, are applied without prejudice and means better stability for everyone using our service.

Professional and reputable hosting from a company you can trust!
Second to none

Super friendly, knowledgeable - anything, anytime, nothing is too much for them and they will happily do the best they can to cater to your needs. I found them whilst looking to expand the locations I offer on an existing business where uptime, speed and reliability is a must and has to be second to none. I am happy to say that hostworld ticks all the boxes. Al

Excellent service!

Thank you very much for the excellent service I have received from Hostworld. My emails work very well following the help you gave installing my new domain on all my devices. My internet and email security has been greatly enhanced, my server space increased (I should have done that ages ago) and I have confidence in my new hosting package. Alison

Just amazing

I just want to say a massive thank you. I run a music forum and people begged me to do a virtual party for the easter weekend during the COVID lock down, live DJ's etc. After many hours of trying different providers, youtube, facebook, twitch and so on... i was ready to pull my hair out. The only time i had to contact support was to say WOW. Etienne
