is 1 vcore and 1024MB enough?

ArkasArkas Moderator

Hi everyone!
I found this site while looking for coupons for a VPS on Google.
I have a forum that has been hosted at a friend's dedicated server for about a year.
I now need to move it as he can no longer host my site there as he is changing dedicated servers through his company and he can't host my site.
is a VPS with 1 vcore and 1GB of RAM enough to host a forum with about 5k-7k unique visitors per day and about 100 concurrent registered members?
Can I also host 2-3 other wordpress sites in such a setup?
TIA!

  • It depends whether its a shared or dedicated core; and what the core is. 1 core of Core2Duo isn't much use.

  • WHTWHT Member

    From experience: 2GB Ram for vBulletin are not enugh!

  • 1 Core to 1GB is a strange ratio. More cores are usually provided with more RAM. If that 1 core is shared then we really need to know what CPU is running.

  • ArkasArkas Moderator

    I have no idea... What do they mean when they say 1 core or vcore?
    Does that mean that If a server has 4 cores, I get 1, right?

  • Which forum software as well?

  • ArkasArkas Moderator

    Thanks for the help! How do I know what CPU the VPS is runing on?

  • ArkasArkas Moderator

    its running on smf forum software

  • Arkas said: How do I know what CPU the VPS is runing on?

    Run the following in SSH

    cat /proc/cpuinfo

  • ArkasArkas Moderator

    ok, i'll do that, thanks!

  • I have an IP.Board forum with about 2k uniques per day, running on a 512+256 box with an E5 core.

    I do notice slowdowns sometimes after moving from a box with access to 24 cores, but IP.Board is quite a heavy/bloated forum and it uses plugins like a shoutbox open to everyone, so I guess you could squeeze it onto a 1core/1GB (if it's a decent core) box if it's just basic SMF and Wordpress installations.

  • Each one of those is a core, so you would have access to 4 3.3 GHz cores. Should be adequate.

  • Likely a E3-1240 should be fine

  • ArkasArkas Moderator

    Thanks! I feel better now!

  • Yeah you have access to 4 cores there

    Thanked by 1Arkas
  • ArkasArkas Moderator

    How can I have access to 4 cores when it says 1vcore?
    Do I have any core that is allocated only to me?
    I know I must sound stupid...I design websites, not much of a techie.

    Overselling / Hyper-Threading

    (HT is basically a form of software "virtual" Core, but nothing like a real core)

  • ArkasArkas Moderator

    Well that's not good :(
    I thought it meant I have access to 1 core.
    Heck, I can get a dedi for under $60...

    Not really. What the OP has there is four cores (KVM). On a processor with hyperthreading, 8 cores are shown and 8 can theoretically be added to a KVM guest, but four of them are virtual (Hyperthreaded).

    What I'm getting at is that from inside the VPS, you can't distinguish what is real or virtual (Hyperthreaded) and I don't know how overselling would come into it.

    Your provider is giving you four KVM virtual cores, they clearly wrongly advertised it as one or set it up wrong. Either way you have access to four so you win :)

    I doubt any of them are "Dedicated" to you, though. They're probably shared.

    Thanked by 1Arkas
  • Unless the provider specifically states that the cores are dedicated then they will just be shared across all the users on the server. Your processes are fighting to CPU time like everyone else.

    Thats why I mentioned at the start were they shared or dedicated cores. We sell a dedicated core VPS product which is aimed at people who want to max out their core 24x7 without interfering with others on the same system.

  • Arkas said: Heck, I can get a dedi for under $̶6̶̶0̶ $10...

    Corrected that for you

  • ArkasArkas Moderator

    a dedicated server for $10...... Seriously?

  • ratherbak3d said: Not really. What the OP has there is four cores (KVM).

    they can still be oversold. they are not "dedicated" as such.

    I know that, but I read it as this.

    Why do I see four cores? > Overselling / Hyper-Threading. When actually neither of those answer his question.

  • @Arkas said:

    Yes, some of the cheapest and fine dedicated providers are Kimsufi, DelimiterVPS, Dacentec and ServDiscount. But for 10$ you won't get a cpu which is able to serve all these visitors / users quickly so it'll be better going with a VPS first of all. Further you should be (more) experienced when having a dedicated in terms of Linux, server management and properly security.

    Thanks. I prefer your honest opinion. You are correct.

    They do but rather indirectly.

    Angling for thanks is never a good look.
