Huaxin Yun clothes vps vps important parameter virtualization technology is fundamentally a virtual machine, are certain virtualization technology built. Currently most used virtualization technology Xen, OpenVZ, Hyper-V, vmware. Below for useful parts vps rough talk about, learn more extensions can be found in the text after reading "xen, kvm, vmware, hyper-v virtualization technology more "and so on. Where OpenVZ is operating system-based virtualization technology, it runs with the efficiency of the real machine (physical server) is almost the same. But do not happy too early, the performance vps are from the host, because there are a lot on the host vps, vps every available resource in fact is not very high, it depends on the specific properties of the host hardware itself how to run a number of top vps. OpenVZ has several notable features: no swap swap (virtual memory), the agreement can not run pptp vpn, easy to overbooking. (New version Openvz already use swap in linux 2.6 or later, and also can be a good run vpn pptp protocol) on overbooking: Suppose the host has 16G of memory, but out of 20 1G memory vps, are selling out; and that 20 years have shown 1G memory vps cloud server, which is overbooking. Indeed OpenVZ overbooking usually more severe! Xen, is a semi-imaginary-based technology called like, a real machine performance than a loss, but the virtual machine out of the system with real high similarity with swap, you can run the pptp vpn, not easy to overbooking. On the xen linux, you can replace or upgrade the kernel; reportedly even then installed a virtual machine environment virtual vps (not personally seen, but even if successful, the performance is extremely low, there is no practical).

Shenzhen Huaxin Yun vps other related memory, hard drives, flow , IP, Ping and other value memory size, hard drive capacity, monthly traffic, needless to say, is certainly the bigger the better; of course, the bigger more expensive. Common memory is generally 256M-1G, dozens of hard G, the monthly flow of hundreds G. Independent IP, usually a cloud server ip, not enough can be purchased separately in general. There are some foreign vps an ip v6 address, but not the development of universal IP v6 currently not practical. Server location, certainly from the main user groups closer the better, from the past network delay is small, fast speed; this is not absolute. Ping value, the general quality of the test network, we will look to rent ping cloud servers, see the response time, packet loss rate, the smaller the better, but sometimes ping value is very low, no loss, but the speed is not fast. So ping value is an important reference, but do not be too concerned about, after all, is not used to ping a vps play. Establishment of Small Memory 128MB VPS Website method small memory VPS station can also be used, including wordpress, etc. You can also fully support large memory, as follows: 1. Reduce the number of php-cgi process defaults to 5 build cloud server, it is recommended to reduce to 3 or 4, I opened two processes modify: Edit /usr/local/php/etc/php-fpm.conf, modify max_children value, restart PHP-FPM (/etc/init.d/php-fpm restart) that can take effect. 2. WP Super Cache Cache plugin and enable the station's pre-caching static mode. 3. Use the debian consume less memory and other Linux systems.
