    It's not an high tech server but it's not close to sloppy either. It does it's job very good for a great price, I own multiple dedicated servers and even more VPS'.
    Thanks for the info btw, got a little worried.

    I'm jelly, any special trick? what brand is it?

    VMWare Fusion seems to ignore the conv=fdatasync part.

    It's the FUJITSU MJA2250BH FFS G1 that came with my MacBook Pro.

    Such 2.5' 5400rpm drive can only give a result around 60 - 70 mb/s in real world test.

    dd test sometimes does say nothing; I did a very careful benchmark regarding the "computational capability" of VPS on a buyVM OVZ512 box with IO at ~183Mb/s and a 123systems OVZ192 box with IO at ~43Mb/s. I installed R software, a very well-known statistics utility, on these two boxes and ran a pre-processing analysis on 564 microarrays in CEL.gz format which includes the processes of decompress the data files, loading images and scaling the signals. The compressed data size is 1.6GB. I used the time command to record the computational time. The results are very interesting; the buyVM box performs worse than that of 123sys, please see attached,

    I was really disappointed with the benchmark results, but not sure what to say. Perhaps I need to ask buyVM for a downgrade on the box. :)

    I did the test again; it seems that things went worse on my buyvmOVZ512;

    real    8m10.887s
    user    6m32.293s
    sys     0m40.195s
    

    meanwhile, the 123sysOVZ192 does not change much,

    real    4m47.281s
    user    4m37.918s
    sys     0m8.584s
    

    In comparison with 123sys one, my box with buyOVZ (2 CPU cores; Intel(R) Xeon(R) CPU L5520 @ 2.27GHz, 2260.936MHz and 4GB cache) consumes more system resources but gives worse performance than that of 123sys (2vCPU, Intel(R) Xeon(R) CPU E5520 @ 2.27GHz, 1133.373MHz, 8GB cache)

    Anyone knows the reason? your explanation is appreciated!

    You are cheating.... :/

  • FranciscoFrancisco Member, Top Host, Host Rep

    @tinray I'm still needing to get around to your ticket to see if there's something I may have screwed up in one of the newer pony kernels.

    It's quite possible I swapped something, or there's a setting on your VM, that i'm not noticing.

    If you're able to give me a bit of time to look into it, i'll check into it more later today after I'm done prepping the new router.

  • please consider my ticket #249702. I did discuss with Anthony regarding this but we not yet come to an end lately.

    My latest test;

    buyVM512

    real    7m26.194s
    user    6m21.136s
    sys     0m43.071s
    

    123sys192

    real    4m28.631s
    user    4m24.740s
    sys     0m3.040s
    

    I would upgrade my box to a 4core plan but I am much worry about the performance of the box. Once I upgrade it but find out it performs badly then I just leave it unused. I currently have a some of such boxes.

    Is that your localhost :S Why didn't you change the hostname.

  • tuxtux Member

    It is default host name on Arch Linux template.

  • @Infinity which node are you on, open a ticket that is not normal.

    Thanked by 1shelveena

    semoweb said: @Infinity which node are you on, open a ticket that is not normal.

    I don't really know as I am not the account holder and haven't done and when I traceroute it nothing happens, it is my ISP's problem. It all times out for lots of other servers in different datacenters.

    64.31.44.147 is the IP, the VPS has had lots of problems, not all SemoWeb's fault, we got lots of attacks etc. our server very recently failed to start up properly, we would reboot it and it would power itself down again, we hadn't exceeded our BW limit like we had done previously. We bought enough BW.

    We are going to transfer them all to a cPanel server soon.

    Thanked by 1shelveena
  • @Infinity Ah, just found it , the vps is not active, the output is a lot higher than you mentioned but still not up to par so thanks for bringing it to our attention and we will be reviewing that node now.

  • InfinityInfinity Member, Host Rep

    Our VPS is down yet again.

  • @Infinity Your comment is towards the vps with us?

  • InfinityInfinity Member, Host Rep

    Yep

  • @Infinity, per the Ip you supplied above you may want to speak with the account holder as this is not in an active state I cant say much as your not the account holder.

    How ever if you are added or have the login details to the client area you can also submit a ticket to find out more.

  • InfinityInfinity Member, Host Rep

    Nope. The server keeps going offline then back. Nothing to do with anything we are running. As far as I'm concerned this is rubbish service.

    As for the account holder, he is on holiday at the moment (yep a long one).
