XCache is free and open source software, takes little time to install and provides a substantial return.
If XCache and XDebug are turbochargers, memcached is a jet engine.
If you use Linux, your distribution may already include XCache or may make it available to you in a prepackaged form.
如果使用Linux,則其發行版可能已經包含了XCache或者已經將其以預先打包好的格式提供給您。
