In addition to generally not according to the written parameters to carry out the space configuration, there are some less well-known way of the flicker:
Basic parameters
This is the oldest way to cheat, said to limit 10% of the CPU, the actual limit of 5%, which is the target of things and the actual is not the same, supporting components are not complete. This kind of flicker of space quality slightly understand generally will have more obvious feeling to "poor".
"Super Sale"
Simply put, if a server 100G, if all is 1G sell, can sell to 100 people. But these 100 cannot all use 1G, therefore, the space merchant then puts 50 station in the inside (space has the position, the nature is puts under). Everyone looks at their own space is 1G size, the actual is not necessarily, of course, almost full time, the space Chamber of Commerce to make flexible adjustments. But this "super sale", undoubtedly reduced the cost of space: Originally 100G server can only be sold to 100 people, but actually sold to 150 people. The disguised cost reduces, lets the price be cheaper, the profit can be higher.
Cutting”
This is my own name for this behavior, which is most common in foreign space. In the famous GoDaddy space, 150G space is probably more than 400 yuan (very cheap), or unlimited build station. So early on someone started this idea, sell a 150G space, cut into 1G a station to sell, 1G if 100 yuan here can earn 15000 yuan (looks really very hi). But the person who buys this kind of cutting product, have FTP at most, have no backstage management, also have no customer service and legal safeguard; Want to bind domain name What's also want to find the seller. If the seller wants to close your station, it is so simple.
VPS
VPS (Virtual Private server) technology, the division of a server into a number of separate virtual exclusive server services. Each VPS operation and management are the same as a stand-alone host, can be distributed independent public network IP address, independent operating system, independent super space, independent memory, independent CPU resources, independent execution program and independent system configuration. In addition to the user can allocate more than one virtual host and unlimited Enterprise mailbox, more independent server function, you can install the program, separate restart the server.
The VPS itself is a good thing, just the people won't give you so good. Since the VPS is a virtual machine, then it is the bottom of the server. Originally my 23ting.com used a foreign VPS, the result is self-evident! We can, imagine the virtual CD-ROM on your computer, which can replace the disc. If you run several virtual optical drives, the computer will always be too much. If a server has more than one VPS, then the server will always be too much. And the parameters of the VPS is virtual, false more easily: such as the size of space, or to rely on the size of the server's hard disk, the actual hard disk is only 100G, it can be virtual to you 100G, but the server can be more than 1 VPS Oh. This thing is fictitious, the probe also cannot investigate, wait to be fooled.
Of course, this also has a good faith operating vps, who is? I don't know, I didn't see it anyway.
Combined rent
The rent is a few people together with a larger space, occupy buy a lot of price concessions (relative to buy more space, the cheaper price); In addition to the possibility of encountering "basic parameters", the biggest problem is being dragged down--as long as there is a violation, you may be implicated; there's a very eating resource, may be affected by your own site access. Of course, this is not the problem of IDC, but the IDC will be a separate space, as mentioned above "cutting", is actually a kind of rent sheets sold performance.
So, the person who cheat is charged more money, the person that is fooled can only bet his luck: space whether still can use.
