The loading speed of the website is very important for a website, its own use from different vendors of the server, the comparison of advantages and disadvantages, the disk, memory space, and so feel is not the case, the main response speed has a relatively large difference, intuitive look more troublesome, so write a simple page directly test loading speed.The H

as a timer to tell us how long the local machine needs to synchronize with the remote server once Poll: How much time the local and remote servers synchronize (in seconds). The poll value will be smaller at the beginning of the NTP run, and the frequency of synchronization with the server will increase, as soon as possible to the correct

performance evaluation of the server CPU subsystem, while the latter focuses on performance evaluations of IO subsystems. We used the SiSoft Sandra Pro sr2a to test each system, which is more familiar to the average reader, and can even use the shared version to test its own system directly, so there is a more intuitive concept of our

We know that the decision maker who is responsible for purchasing the server, when choosing a product, usually focus on "see parameters", such as frequency, memory, scalability, in fact, focusing on the product itself, to see whether its technical indicators are leading: one or more CPUs, dual-core or quad-core, the memory channel is 1GB or 4GB. In fact, this angle of observation does not have much meaning. Eager to step on the information highway us
