I don't understand the clock speed of my dedicated

Hello!

There is a difference between what cpubenchmark.net reports and what my system says about the clock speed of the CPU (Opteron 1356):

Sorry if this has already been asked.

Thanks!

  • Speedstep (or whatever AMD's equivalent is).
    The CPU clock is automatically reduced when the CPU is idle, to save power. When you put some CPU load on it it will automatically speed up the clock.

  • CoolnQuiet or some form of power saving may be enabled.

    Don't worry, only a hundred times or so.

    Your best bet is to disregard the answers above and make a ticket asking why they scammed you on the CPU MHz

  • Debian does the same thing on my laptop.

    Set cpu governor to performance instead of ondemand.

    Yep, just run:

    for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n performance > $CPUFREQ; done

  • I'm getting this on a time4vps vps:

    processor       : 0
    vendor_id       : GenuineIntel
    cpu family      : 6
    model           : 63
    model name      : Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz
    stepping        : 2
    microcode       : 46
    cpu MHz         : 1173.995
    

    I'm hitting the CPU pretty hard with 90+% utilisation. Is this something I should be expecting to see?

    If im correct they are using OpenVZ, so probably have the plan CPU limited to a % of a CPU core to stop someone abusing all CPU resources.

  • I guessed as much... So much for 2x 2.4ghz dedicated cpu as advertised, but I'm sure they will justify it by redefining what a dedicated cpu is.

  • Good luck getting a refund for your CPU rip-off - I've been trying to return my new Porsche for a month because it doesn't always drive at 120mph but they keep saying its normal.

    That's not a low end car. The example that doesn't make sense.

    Our monitoring system limiting CPU usage, due to the fact that your VPS is abusing node CPU with buggy script(s), because you have constant 90%+ load. What application(s) do you host?

    I don't understand this, if you offer 2* 2400Mhz cpus, as DEDICATED then why cant they fully utilize them? There are applications that may need to max out cores.. Transcoding for example.

    Of course you can. But do not ignore the fact that you have VPS, not dedicated server. In order to stop resource abuse, we do not allow to use 100% CPU more then 1 hour constantly. Usually, most applications require 100% CPU for short period of time.

    For video transcoding tasks consider dedicated server.

    Heh, don't ask a VPS provider to explain what "dedicated" means exactly. Or at least, if you do, be prepared for a fairly off-the-wall interpretation.

    Good enough that the CPU is theoretically capable of that processing speed.

  • Well, there are two problems here. One is false advertising by the provider, using the word "dedicated" for something that is not dedicatd. Second is unrealistic expectations by the client. You can't reasonably expect to get two dedicated CPU cores at that price.

    We allow to use ordered CPU resources 100%. But we will definitely not allow to abuse it by constant hammering with services like crypto currency mining, video transcoding or any other service who requires fully dedicated environment.

    Soon, we will introduce few solutions for high-end demand! :)

    See what I mean?

    I think what he actually meant for the first part is something like "we 100% allow the use of ordered CPU resources".

    So, we learned @time4vps throttle the CPU to 50% of core on detecting 60min+ maxed out cpu, to maintain QoS for everyone.

    I actually prefer this provider approach rather than suspending the VPS or asking client to move overnight.

    Wable does something similar; plus they auto-raise a ticket to let the client know about (last cpu event was over a year ago from runaway rsyslogd before @incero fixed the template)

    I've tested backing up my Kimsufi to time4vps storageVPS at 90Mbps constant; Total Load-Avg hovered at 0.20 even with SSH overhead. (and that's on a 1.9GHz E5 cpu )

    When combined with encryption-capable backup utilities, @time4vps are brilliant value for money.

    Once they roll out KVM on RAID10 SSD, I'll give that a try too.

    Automation is the way forward for sharing pooled resources.

  • From what I see the CPU freq drops by 10% every hour until bottoming out at 1.2GHz. A reboot will bring it back up to 2.4GHz, so theoretically that can be abused by rebooting every hour. No, I'm not really going to do that :p

    When I started working on my project, I wasn't sure where I will be bottlenecked. Time4vps looked like a good place to start after looking through these forums, great pricing and there was the lure of 'dedicated cpu'. Now I know it's not suitable for my needs so I'm currently waiting for a dedi server I've ordered to be provisioned.

    Thanks for taking the time to search or even trying to use google before asking. It's a pretty nice tool actually, you should try it! Click the link below to learn how to use Google!

    Yes, and now it would be wonderful if they removed the big fat lie about "DEDICATED" cores on 3 EUR VPSes from anywhere on the website and promotion materials. Else this is basically scam plain and simple, it's not dedicated unless you can use 100% of it 24x7 with no limits of any kind.

    Yeah. @time4vps

    IMO, that's a generous system.

    Does the cpuMhz reset to original after, say, 24hrs of low-load?

    Having to reboot is annoying.

    At the moment VPS restart is the only way to remove limitation. We are improving our monitoring system, thank you for note regarding it.

    Do you have services with us? Are you experiencing any problems regarding CPU usage?

    you need to fix your slider price quotes, there is no 8GHZ CPU.
