2010-02-23 11:05web2.0 and web1.0 are different, web1.0 content-centric, so web1.0 do the load just cache the content, using the reverse proxy cache page can solve most problems. and web2.0 encourages user interaction, the content is dynamic, only to do reverse proxy life if the middle rate is low, and the database is frequently written, the pressure on the database. Therefore, web2.0 needs to use a memory cache for web1.0. Memcached high-performance, distributed memory object cache system that reduces database load and improves access speed in dynamic applications. Memcached has been widely used in a variety of software, such as Nginx, MySQL one, server-side installation using Weget download Libevent and memcachedlibevent:http://monkey.org/~provos/ libevent-1.4.9-stable.tar.gzmemcached:http://www.danga.com/memcached/dist/  Memcached-1.2.6.tar.gz1.

Source: http://willko.iteye.com/blog/332993netseek (2009-9-10 11:16:40) memcached client libmemcached, when processing value more than 8k of data, the speed will be straight down, In Http://lists.tangent.org/piperma. ovember/000484.html, you can find the answer because Libmemcached buf is too small to find the source file Memcached_ Constants.h, modify the # define Memcached_max_buffer 8196, change to the appropriate size, recompile, install, and you can. Libmemcached is the interface of the C client library to the MEMCACHED server. It is designed for lightweight memory usage, thread-safe, and provides a way to get a full server-side approach. It also employs a variety of command-line tools: Memcat, Memflush, MEMRM, MemStat, and memslap (load generation). The library has been designed to let different hashing methods pair the keys, split the keys, and use a uniform hash distribution. License: BSD License (revision) change: Fixed descending hash key. The corrected assertion is that the host_reset () called by the memset () is not well caught. Fixed an issue where clearing blocked I/O has been stacked. Supplementary MemStat. A new API for flushing water. memcached Simple Tutorial This is a project-based article: memcached is a tool for fast data access, and Wikipedia and Facebook use it to improve speed. The specific situation can be wiki.c/c++ inside use memcached originally is very simple thing, but is no one said, do not want me to read Libmemcache instance code just line, Manpage also didn't say clearly (but also have to see). If you want to use memcached, proceed as follows: 1 install memcached You can go to the official website to download, or sudo apt-get install MEMCACHED2 Test your installation, such as running memcached-d-M 64-l 127. 0.0.1-p 12300-d for background,-m 64 means using 64MB memory,-l 127.0.0.1-p 12300 means listening 127.0.0.1:12300 port no message is running successfully 3 installation libmemcached This is not the AP T anymore, because there's no preciseLibmemcached bag, go to the official website to download it. This thing also need to libevent, this can not apt,libevent install the time best loaded into/usr/lib inside, otherwise libmemcached still can't run.　　4 Test libmemcached Find a file such as test, and then run MEMCP test--servers=127.0.0.1:12300 to copy the test into the memcached managed memory.  Memcat Test--servers=127.0.0.1:12300 See if that file was just.
