    Is this a KVM or OpenVZ VPS? If its KVM try enabling virtio in solus.

    Your speedtest link http://www.speedtest.net/result/3572436661.png
    shows the ISP to be "2267921 Ontario", and after some investigative work...
    surely that's CloudAtCost? http://lowendtalk.com/discussion/28041/cloudatcost-50-off-today-1-core-512mb-10gb-vps-for-17-5-one-time-payment/p1
    I don't think given the nature of their offer anyone would be too shocked to learn their VPSes are this oversold. But in any case, their ticketing system is that way =====>

  • ChuckChuck Member

    I don't think their support can help me if they already oversold.

    I have a bluevm CA KVM VPS with the dd result about 8MB/s...

    Woah, that is low.. To login it must take hours.

    What do you need over 9.3MB/s disk I/O for?

  • I don't see why there is a problem it's not that bad for a 1 time vps.

    A disk I/O of less than 500 Mb/s & anything other than SSD(both of these not needed in 99.99 % cases) is not acceptable at LET, thanks to those providers who try to fool customers with DD porn which is basically due to the controller cache memory. False advertising & fooling customers FTW.

  • I get like 11MB/s from my OVH VPS, and it's never impacted the performance of the box.

    The OVH Classic VPS range have disk I/O limited to around 11MB/s.

    Disk I/O is not an issue in 99.99% of cases where providers knows what he is doing

  • I am happy with my 11 MB/s from the SDHC card on the Raspberry Pi. It's weird to see VPSs being slower than that.

  • @1e10 said:

    Yeah so I've heard. Small price to pay for an excellent value VPS from a reputable company

  • J1021J1021 Member

    I think I prefer VPS hosts imposing limits on I/O and network speed (e.g. VM restricted to 100Mb/s with node connected at 1Gb/s) as it creates a more stable environment.

    Yeah don't worry. I've had my fair share of low Disk I/O and logins while using Host1Free. Average Disk I/O with them is 20 MB/s on a good day.

    I once got over 100MB/s on my H1F VPS... I was so happy, then it dropped to 8MB/s...

    Thanks for the advice.

  • Okay, woah, my VPS with the highest IO is at GVH. Well, that's a plot twist.

    Sorry if that's really off topic, I never tested my I/O before and found that really surprising.

  • PwnerPwner Member

    @linuxthefish @eddynetweb

    I know this is a little off-topic, but on your H1F VPSs, do you need to shut them down from time to time to clear out the memory cache? I find mine lags after a while and I have to do the 10 second shutdown.
