    My latest VPS -Amazon Ireland- disk I/O looks a bit poor, but otherwise quite good.

    @finlandvps - that's with no load....right :-) ?

  • @asterisk14 - the server has load at 1.22 currently where the kvm instance is running, but the KVM didn't have much load.

  • Just being curious, what is the acceptable lowest disk i/o for the leb server? Lets say 20MB/s -25MB/s... do you guys think its still acceptable?
    Thanks..

    If your IO is that low something has to be wrong.

  • I find it usable at 30, somewhat problematic (lags) below 20 and trash below 15.
    That being said, it is a long time since i saw such low numbers, most recently had the host1free VS some 6 months ago that was about 30 and was pretty cool, i didnt feel any lag on it.

    At home I have a CF instead of hard disk on a via c7 I use as a router with more VMs on and that is below 5, but works well as router, only you can feel it lagging when you login and it does not do much IO otherwise.

    I think anything below 100 is unacceptable. I don't buy unless it's ssd cached or better now xD

  • I think 50 MB/s or above is reasonable. It all depends what you plan to use it for.

    100MB/s? Curious to know what applications/services that you are running on the VMs...

    I've just noticed that it lags for me when it's sub 100mb/s

    Do you check the iops?

  • @Xaki I know which node you're on and we have some RAM + CPU Upgrades + that will be done on that server either later this month or early next month, we'll also be swapping out the ssds for bigger ones which should improve the caching.

    Just FYI that server can push over 1.2Gbps, hardware being the limitation.

    I don't know if that is true or not, what I know is that I paid for a service and after 1 week my VPS got this disk performance .... I can't use it, is slower than a snail.

    Ofc I will leave EaseVPS and I will not recommend EaseVPS to my friends and everyone I know... I can't recommend! I don't have complains about you (jacob), you are a nice guy, and always available to talk with me and to solve the problems, but this situation...
