Building a high-performance web site Reading Notes: Dynamic Content caching

Dynamic Content caching mechanisms include full page caching, partial caching, and data caching. Cache focuses more on policies, that is, the cache hit rate.

 

1. Page Cache

For dynamic web pages, the cached content is actually the HTML output by dynamic web pages.

1.1 smarty Cache

Using smarty cache, reading cached files on a disk consumes a lot of disk I/O overhead and CPU and memory swap overhead.

1.2 APC & xcache & memcache memory cache

The APC cache and xcache cache are very efficient and use local memory to store cached data.

Memcache provides better storage scalability and can be used to build multiple cache servers.

2. Local no cache

Use the register_block method of smarty and the {dynamic} tag.

3. Static content

3.1 direct access to cache

Fastest speed

3.2 update policy

There are two types of static content update policies: (1) regenerate static content during data update. (2) regularly regenerate static content

3.3 Local static
