Since the specification and number of information points of large, medium, and small computers are determined by host devices, wiring designers generally only collect the types and quantities of their information points, rather than wiring them. Therefore, the number of information points discussed in cabling planning mainly comes from server cabinets. Before counting the number of information points, it should be noted that the number of information

Asynchronous Io, APC, Io completion port, thread pool, and high-performance server (APC)Alertable Io provides a more effective asynchronous notification format. Readfileex/writefileex provides a callback function (APC process) when sending an IO request. After the IO request is complete, the callback function will be e

Very early like on such a set of data backup system, daily use of the original software backup and manual backup method, there are always some not too convenient place.Coupled with the expansion of enterprise scale, the system increased, business data is also important. No interruption and data loss. This is not, because of the system data backup considerations, the company this time to test this data backup storage cabinet function.The first contact

A tt server has been built over the past two days. It is a cache server written in Japan. The performance is said to be much higher than that of memcached. The specific parameters are unknown. The first task of the past two days is to build a Linux system. The main reason is that the Linux system is too weak. 1. install it on your own under the root account. The installation is smooth, and everything is

Tokyo cabinet tyrant supports master-slaver and master-master distributed deployment. However, because master-slaver needs to manually set the master after the master is down, this method of Cold Start is not very good. In addition, the master-slaver method is basically used to process multi-read and write operations. For projects with a low read/write ratio, it is more suitable for the master-master mode. Assume that two machines are distributed

I have seen some articles saying that the efficiency of APC on the same server is seven times that of Memcached, and the efficiency of APC is higher than that of Memcached. As for how fast it is, I wrote a small program to test it. The code is as follows: $ Memcachehost = 'localhost ';$ Memcacheport = '000000 ';Function microtime_float (){List ($ usec, $ sec)

Eaccelerator seems faster than APC, however, if you are running multiple instances of Apache on the same server, you will understand the second caching utility PHP uses. I use two APC and Eaccelerator, the APC seems to be getting better, only within the last 3 months (since 01/2006).Note: This accelerator may become be

unnecessary thread switching and control the number of concurrent threads to the number of CPUs.What we really need to care about is Io computing. Generally, network server programs are accompanied by a large amount of Io computing. The way to improve performance is to avoid waiting for the end of Io, resulting in idle CPU. Try to use hardware capabilities to allow one or more Io devices to run concurrently with the CPU. The asynchronous Io,
