If you want to replace APC and use both of it's features a) PHP opcode
caching and b) general purpose shared memory cache, you will need both
packages. OPCache replaces feature a), while APCu replaces b) using an
identical API (no need to modify you source already supporting APC.

In our hosting farm we usually only use APC as opcode cache and
memcached for general purpose caching. While on single machine
installations we use both APC features.

Title:
  Zend OPcache package for PHP 5.2+

Status in IUS Community Project:
  New

Bug description:
  Using a PHP accelerator gives a drastic performance improvement in a
  PHP environment and the PECL package APC
  (http://pecl.php.net/package/APC) has historically been one of the
  best accelerators around.

  Latest stable version of APC is 3.1.9 but support for PHP 5.4 (current
  PHP stable) wasn't added until 3.1.10-beta and even latest version of
  APC 3.1.13 is considered beta.

  I don't believe we'll see much further updates to APC either as it has
  been decided that PHP 5.5 and onwards will include Zend OPcache
  (https://github.com/php/php-src/blob/php-5.5.0beta1/NEWS) which was
  recently open sourced (https://github.com/zend-dev/ZendOptimizerPlus)

  Zend OPcache is available, stable and supports PHP 5.2+
  For me it seems like a natural addition for IUS to add as a package at least for PHP 5.4, but perhaps also for older versions.
