Hey, Firstly, i would like to say thanks for this great thread, i find it relevant to me, as im currently running a mid-end VPS, but i do have one question, My VPS has a 50% share of CPU and the server its on runs AMD athlon 64 Dual Core 2800+ , does that mean that i effectively have access to 1 of the 2800+ processors on my own, or does it mean i have access to effectively 2 half processors ? this does confues me, as in cpanel, it says 1 cpu.
second thing, you might of answered this question earlier, but i have 512mb dedicated RAM, and its burstable to 1GB (what does Burstable mean EXACTLY, i have heard a couple of rough definitions but im still not sure)
thanks,
amchost : )

Especially if you aren't paying a lot for your VPS, you may want to question whether you really are sharing the server with just 1 other VPS, because there might just be quite a few others without your knowledge.

It should be safe to use it for peak usage, but if you consistently use more ram than what's guaranteed to be available, then you are basically putting your VPS's stability at risk.

Thanks for the reply, My VPS is openVZ based so i dunno if that allows me to see both cores, or not .
Thanks for the advise on the scam, But the server is run by someone i know, and I trust him, plus, its a custom package, not something i signed up for . I suppose its quite a high spec Package, but you seem to be able to get some VPS machines with 1.5gb garaunteed RAM, 2.8 GHz, 100gb space, and 2000 GB bandwidth.
To be honest with you, if i wanted a machine like that, i would go for Dedi every time the prices are similar.
Thanks for the info on Burstable Ram, I dont use above 512 mb anyway ( as a rule ).

With openVZ you should be able to see both cores. As far as I know it's not possible to let openVZ only show you one of the cores, unless if that was recently added to the software.
It could be that the machine maybe isn't a dual core machine afterall, or it could be that the host has turned of dual core functionality in the BIOS. Either way, your best bet is to simply ask your host about it.

Since linux is opensource, ultimately everything can be fabricated. It's unlikely that they have done that though, especially since you indicated you trust the host.

There are many threads on the VPS forum on which VPS technology works best.

Hi,
Thank you very much for your article..
I am planning to buy a VPS for my vBulletin forum.. It's an average forum with around 50 - 150 users online in last 15 minutes.. The D is around 200 MB & i'm using vBSEO also.
What config you recomend for a VPS package? Will 256 enough if i'm using cpanel also?
Thank you..

If there's a lot of database activity, I would recommend to go for 384mb RAM (especially considering that cPanel by itself uses up 100-120mb ram). 256mb should probably work too, but 384mb would be safer.
What you could consider is to get a VPS with 256mb first and monitor your resource usage. Then if it turns out that you need more ram, you could simply upgrade the VPS
If you aren't sure about things like these, it's probably a good idea to go with VPS host that provides a managed solution, as they should be able to assist you with optimizing your RAM usage and make recommendations on what to do.
Good luck!

Haha very good. I usually never buy a vps unless the company owner was a member of WHT.

Usually Plesk uses the least. Plesk comes with the benefit that it's based on a templated architecture, which enables it to share the resources with all other Plesk VPS's on the same server. Thanks to that, the usage per VPS is lower - but this is only really effective if you run mutliple Plesk VPS's on the same machine.
It's not really possible to give any hard numbers for that, as that depends on a lot of factors. It depends on the size and activity of each VPS, and how much the server can handle (which relies on CPU, disk I/O and RAM). The only way to find out what the limitations are, is to test your configuration by creating a certain amount of VPS's on the server and push some load onto them - and then just monitor the load and lags.
