6. How much bandwidth enough?
To tell the truth, as long as enough memory, configuration, traffic in general enough. Do not go to corrupt what is not limited to traffic, it is illusion. In the event a large flow rate (most likely because of limited flow of the most attractive big eyes), always occupied bandwidth, go die on the waiting depressed. In short, traffic is not more than good enough. As for how to calculate their own websites about how much traffic can consume, you can refer to this article: http://kangzj.net/how-many-gigabits-do-i-need/.How to choose a foreign VPS

According to my observation, about two kinds of CPU-sharing methods for a Equal Share, literally meaning that we should split the use (of course there are also big risk that may be encountered); the other, limiting the number and frequency of nuclear.

Choose a high-quality high-speed host is very important. As the virtual host host resources to support the environment, all sorts of restrictions, many owners choose VPS (Visual Private Server), this article, we will come together to talk about how to choose a foreign VPS.

However, I use the experience, Xen performance in general than OpenVZ good. As for the main reason, I think, not because of how good the performance of Xen itself, but Xen is not easy to oversold (based on Xen for VPS would be the same as the real machine with memory, Cache disk, while OpenVZ’s VPS will not).

2. How to choose VPS providers?
2.1 to see word of mouth
Select the host providers, first of all look at word of mouth (down machine frequency, ticket processing is timely, it had lost customer data, etc.), this I will not say human flesh can be the next host provider, there’s places to go and see, that is, WHT (WebHostingTalk), a super-busy place, Kangzj no more to say.

Any foreign host, IP there is always the danger of being closed. If sealed, add IP is a fee, if you can not add IP, then the VPS essentially scrap (I used one of the VPS, is not allowed to add or change IP).
Now fast, the year is not necessarily faster. Linode Fremont room is a vivid example, of course, free of charge for room Daohai Linode it say.
VPS Business cases escaping with money instead. Such a thing is not without precedent, though extremely rare, it is not without, the case went to the character that were on the … …
In short, in a word, this may be the year a lot of things you can not think, you may lose money.Month by month, feeling dissatisfied with the at once, more comfortable.How to choose a foreign VPS

As everyone good or rely on, not a very good comparison, everybody will think clearly on the O of.

Delay (ms) position (United States)
160-220 West Bank (in LA as the representative)
220-240 Central (in Dallas as the representative)
For more than 250 East Coast (in WDC as the representative)
ping does not mean anything, it only indicates the server response time, tens of milliseconds basic human imperceptible. Select the server ping is not the first standard. Ping in Hong Kong can be said that all foreign hosts were the best, can be less than 10ms,

Another point to note is that, Xen for VPS in general can be directly opened pptpd and OpenVPN for VPN, and OpenVZ the VPS can only be opened OpenVZ’s VPN (if the default did not open, will need to contact customer service opening tap / tun and IPtable).

7. Monthly payment or yearly?
Although the general annual pay will be concessions, but still very much the proposed monthly payment. Why, for three reasons:

3. Select which virtual technologies VPS?
Virtual Technology is the most used Xen and OpenVZ. According to Rashost say “Based on XEN in Linux VPS (Para-virtualized VPS, semi-virtualized VPS) performance is superior to other virtualization technologies”, while in a number of forums have also heard good performance OpenVZ over Xen his words, a time-division unclear who is right.

2.2 a ping, 2 whois, three test download
Many VPS Chamber of Commerce to provide testing IP, the first ping, the delay to see how kind. Generally speaking, the U.S. hosts more than ping are 160ms and the most Acura Acura be a little more than 160ms of. The following table simply the next is not accurate:

This article only discuss Linux VPS, Windows is not the discussion of the context of;
1. Choose which country’s VPS?
Most of the students pursue but there are two points, one point is the speed, another point is stable. Choice is the United States. And then remove the United States, western Canada, the host also can be considered. The United States is the world’s Internet center, hosting business is very well-developed, super-multi-room, VPS providers is plethora, the price naturally is very cheap. The cheapest about $ 5 a month you can win, this is also a number of owners, “immigrants” an important reason why the United States.

Virtuozzo, VMWare are the two charges of virtual technology, poor performance evaluation, price more expensive than the first two. There is also a new virtualization technology called KVM, is said to have done particularly good separation between the VPS performance is also very good, but not yet very mature.

8. VPS’s CPU limited way?
Although the last one mentioned, but this does not mean that one is not important, CPU is the most easily overlooked, but extremely important aspect.

Restrictions on the frequency There are two ways, one is to limit the single-core, to a frequency (eg 500MHz); the other is to multiple cores, each core to a frequency, and then add (for example, to the 5 cores, each one to 100MHz), speaking on the surface is the same.

5. How much memory enough?
This is very hard to say, on a PHP Web site as an example. PV can be used to estimate the size of memory is needed. In general, each day hundreds of IP’s website, 128M memory, you can barely cope with. Optimization settings can refer to Zhang Yan: http://blog.s135.com/post/375/.

4. What is VPS control panel easy to use?
The control panel here that is not the host control panel, but the VPS control panel is used to reload, restart, and some advanced settings panel. The Kangzj view, the panel has discussed the trip, VePortal, SolusVM, Parallel, etc., or VPS’s own development, function also if only a few, not too surprisingly (Linode’s control panel, except to do good, functional super - super-strong). But then again, this panel is not the case, really is not enough, even the crash should be made to restart ticket, too inconvenient.

IP can be found through the IP Whois Which is the engine room, that room’s speed, stability evaluation, in-line comments are certain to be more than that VPS provider. This method can also be found through the test to download, even if the tests do not provide VPS download, download speeds can also experience how kind.
