【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 不少朋友都关心移动下的seo排名，同时也就问关心移动站采用哪种架构的问题，是跨屏响应式还是独立建m站？不少的朋友对独立的移动站，也就是m.youname的二级网站做手机站有不小的执念，认为独立移动站才是最好的，其实不然。独立的手机网站和pc网站，需要在百度做适配，然而很多人都不会操作，会来询问我，这不是要命的，而是当你独立做移动站的时候，容易被百度重复收录，导致网站的权重分散，甚至降权。关于移动SEO，到底应该选哪种方式优化？今天跨屏网Kuaping.com 就深入探讨一下移动优化的三种方式以及如何选择移动优化方式。移动网站大体上有三种方式可以选择： 1、响应式设计（responsive design） PC站和移动站的URL是完全一样的（不管用什么设备访问都一样），返回给浏览器的HTML代码也是一样的，不同宽度的屏幕排版不同是通过CSS控制的。以前也经常称为自适应设计，就是因为排版是根据屏幕宽度自动适应的。 2、独立移动站（separate m. site）移动站的URL和PC站是不一样的，通常用单独的子域名，比如PC站是www.kuaping.com，移动站是m.kuaping.com。当然，移动站的HTML代码（以及CSS）与PC站也是不一样的，是专门做了移动优化的。换句话说，这种方式下

apc vs eaccelerator vs xcache

阅读更多关于 apc vs eaccelerator vs xcache

问题 Im doing research on which one of these to use and I can't really find one that stands out. Eaccelerator is faster than APC, but APC is better maintained. Xcache is faster but the others have easier syntax. Anyone have recommendations on which to use and why? 回答1: APC is going to be included in PHP 6, and I'd guess it has been chosen for good reason :) It's fairly easy to install and certainly speeds things up. 回答2: Check out benchmarks and comparisons: here and here and there 回答3: APC

Xcache var_size error

阅读更多关于 Xcache var_size error

问题 I am trying to use xcache with zend framework to cache the metadata from Zend_Db_Table_Abstract so that describe queries are only called once per table. When implementing xcache into my bootstrap and running the application, I am being presented with the following error: Warning: xcache_get() [function.xcache-get]: xcache.var_size is either 0 or too small to enable var data caching in /home/randall/htdocs/lib/Zend/Cache/Backend/Xcache.php on line 95. I have adjusted the settings in my php.ini

HipHop instead of XCache?

阅读更多关于 HipHop instead of XCache?

问题 Would it make sense to switch to HipHop instead of XCache? Is HipHop ready for primetime or should we wait several months before implementing it? Edit: we are interesting in testing the configuration on a server running vBulletin. 回答1: Let me clear up a misconception you might have about Hiphop and Xcache. XCache works by adding Opcode caching to ZEND's PHP implementation (like APC and friends), while Facebook's HipHop allows for PHP code to be transformed into C++ code and then compiled

问题 I am trying to use either APC or XCache as an opcode to cache my php pages. I am using it with Zend and Doctrine and it's having a problem with the autoloader.

问题 I've searched all over the web for documentation including on the XCache website. I'm new to PHP opcode caching and XCache. I'd like an explanation of how XCache works. I know that it stores compiled php code so that it doesn't need to be recompiled everytime. But how does XCache know when php code has been updated and thus the cache is out of date? How do I know if I need to clear the cache? Does XCache compile and cache all php code on the server? If so can this be configured? What are

XCache works by adding Opcode caching to ZEND's PHP implementation (like APC and friends), while Facebook's HipHop allows for PHP code to be transformed into C++ code and then compiled using g++. It's not possible to run XCache with HipHop as HipHop doesn't depend on Zend interpreter (and doesn't
