Comparison of caching mechanisms

Hello everyone. What do you think about the following caching mechanisms for WordPress?

  1. For full page cache:

a. Redis with compression:

VS

b. Nginx FastCGI with Gzip compression and serve cache from RAM (tmpfs)

  1. For object/database cache:

a. Redis with compression.

VS

b. OPcache Object Cache plugin for WordPress. “This method is faster than Redis, Memcache, APC, and other PHP caching solutions because all those solutions must serialize and unserialize objects. By storing PHP objects in file cache memory across requests, this driver can avoid serialization completely!”

Thank you :smiley:
