+The Zend Optimizer+
+===================
+
+The Zend Optimizer+ provides faster PHP execution through opcode caching and
+optimization. It improves PHP performance by storing precompiled script
+bytecode in the shared memory. This eliminates the stages of reading code from
+the disk and compiling it on future access. In addition, it applies a few
+bytecode optimization patterns that make code execution faster.
+
+Compatibility
+-------------
+
+This version of Zend Optimizer+ is compatible with PHP 5.2.*, 5.3.*, 5.4.*
+and PHP-5.5 development branch.  PHP 5.2 support may be removed in the future.
+
+Quick Install
+-------------
+
+- Compile
+
+ $PHP_DIR/bin/phpize
+ ./configure \
+      --with-php-config=$PHP_DIR/bin/php-config
+ make
+
+- Install
+
+ make install # this will copy opcache.so into PHP extension directory
+
+- Edit php.ini
+
+ zend_extension=/...full path.../opcache.so
+
+NOTE: In case you are going to use Zend Optimizer+ together with Xdebug,
+be sure that Xdebug is loaded after Optimizer+. "php -v" must show Xdebug
+after Optimizer+.
+
+- Restart PHP
+
+Speed Tuning
+-------------
+
+We recommend the following configuration options for best performance.
+
+opcache.memory_consumption=128
+opcache.interned_strings_buffer=8
+opcache.max_accelerated_files=4000
+opcache.revalidate_freq=60
+opcache.fast_shutdown=1
+opcache.enable_cli=1
+
+You also may add the following, but it may break some applications and
+frameworks. Please, read description of these directives and add them on your
+own risk.
+
+opcache.save_comments=0
+opcache.enable_file_override=1
+
+In some cases you may like to prefer enabling/disabling some features
+to avoid incompatibilities at the cost of some performance degradation.
+
+Configuration Directives
+------------------------
+
+opcache.enable (default "1")
+	Optimizer+ On/Off switch. When set to Off, code is not optimized.
+
+opcache.memory_consumption (default "64")
+	The Optimizer+ shared memory storage size. The amount of memory for storing
+	precompiled PHP code in Mbytes.
+
+opcache.interned_strings_buffer (default "4")
+	The amount of memory for interned strings in Mbytes.
+
+opcache.max_accelerated_files (default "2000")
+	The maximum number of keys (scripts) in the Optimizer+ hash table.
+	The number is actually the first one in the following set of prime
+	numbers that is bigger than the one supplied: { 223, 463, 983, 1979, 3907,
+	7963, 16229, 32531, 65407, 130987 }. Only numbers between 200 and 100000
+	are allowed.
+
+opcache.max_wasted_percentage (default "5")
+	The maximum percentage of "wasted" memory until a restart is scheduled.
+
+opcache.use_cwd (default "1")
+	When this directive is enabled, the Optimizer+ appends the current working
+	directory to the script key, thus eliminating possible collisions between
+	files with the same name (basename). Disabling the directive improves
+	performance, but may break existing applications.
+
+opcache.validate_timestamps (default "1")
+	When disabled, you must reset the Optimizer+ manually or restart the
+	webserver for changes to the filesystem to take effect.
+	The frequency of the check is controlled by the directive
+	"opcache.revalidate_freq".
+
+opcache.revalidate_freq (default "2")
+	How often (in seconds) to check file timestamps for changes to the shared
+	memory storage allocation. ("1" means validate once per second, but only
+	once per request. "0" means always validate)
+
+opcache.revalidate_path (default "0")
+	Enables or disables file search in include_path optimization
+	If the file search is disabled and a cached file is found that uses
+	the same include_path, the file is not searched again. Thus, if a file
+	with the same name appears somewhere else in include_path, it
+	won't be found. Enable this directive if this optimization has an effect on
+	your applications. The default for this directive is disabled, which means
+	that optimization is active.
+
+opcache.save_comments (default "1")
+	If disabled, all PHPDoc comments are dropped from the code to reduce the
+	size of the optimized code. Disabling "Doc Comments" may break some
+	existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)
+
+opcache.load_comments (default "1")
+	If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
+	may be always stored (save_comments=1), but not loaded by applications
+	that don't need them anyway.
+
+opcache.fast_shutdown (default "0")
+	If enabled, a fast shutdown sequence is used for the accelerated code
+	The fast shutdown sequence doesn't free each allocated block, but lets
+	the Zend Engine Memory Manager do the work.
+
+opcache.enable_file_override (default "0")
+	Allow file existence override (file_exists, etc.) performance feature.
+
+opcache.optimization_level (default "0xffffffff")
+	A bitmask, where each bit enables or disables the appropriate Optimizer+
+	passes
+
+opcache.inherited_hack (default "1")
+	Enable this hack as a workaround for "can't redeclare class" errors.
+	The Optimizer+ stores the places where DECLARE_CLASS opcodes use
+	inheritance (These are the only opcodes that can be executed by PHP,
+	but which may not be executed because the parent class is missing due to
+	optimization). When the file is loaded, Optimizer+ tries to bind the
+	inherited classes by using the current environment. The problem with this
+	scenario is that, while the DECLARE_CLASS opcode may not be needed for the
+	current script, if the script requires that the opcode at least be defined,
+	it may not run. The default for this directive is disabled, which means
+	that optimization is active. In php-5.3 and above this hack is not needed
+	anymore and this setting has no effect.
+
+opcache.dups_fix (default "0")
+	Enable this hack as a workaround for "Cannot redeclare class" errors.
+
+opcache.blacklist_filename
+	The location of the Optimizer+ blacklist file.
+	The Optimizer+ blacklist file is a text file that holds the names of files
+	that should not be accelerated. The file format is to add each filename
+	to a new line. The filename may be a full path or just a file prefix
+	(i.e., /var/www/x  blacklists all the files and directories in /var/www
+	that start with 'x'). Files are usually triggered by one of the following
+	three reasons:
+	1) Directories that contain auto generated code, like Smarty or ZFW cache.
+	2) Code that does not work well when accelerated, due to some delayed
+	   compile time evaluation.
+	3) Code that triggers an Optimizer+ bug.
+
+opcache.max_file_size (default "0")
+	Allows exclusion of large files from being cached. By default all files
+	are cached.
+
+opcache.consistency_checks (default "0")
+	Check the cache checksum each N requests.
+	The default value of "0" means that the checks are disabled.
+	Because calculating the checksum impairs performance, this directive should
+	be enabled only as part of a debugging process.
+
+opcache.force_restart_timeout (default "180")
+	How long to wait (in seconds) for a scheduled restart to begin if the cache
+	is not being accessed.
+	The Optimizer+ uses this directive to identify a situation where there may
+	be a problem with a process. After this time period has passed, the
+	Optimizer+ assumes that something has happened and starts killing the
+	processes that still hold the locks that are preventing a restart.
+	If the log level is 3 or above, a "killed locker" error is recorded
+	in the Apache logs when this happens.
+
+opcache.error_log
+	Optimizer+ error_log file name. Empty string assumes "stderr".
+
+opcache.log_verbosity_level (default "1")
+	All Optimizer+ errors go to the Web server log.
+	By default, only fatal errors (level 0) or errors (level 1) are logged.
+	You can also enable warnings (level 2), info messages (level 3) or
+	debug messages (level 4).
+
+opcache.preferred_memory_model
+	Preferred Shared Memory back-end. Leave empty and let the system decide.
+
+opcache.protect_memory (default "0")
+	Protect the shared memory from unexpected writing during script execution.
+	Useful for internal debugging only.
+
+opcache.mmap_base
+	Mapping base of shared memory segments (for Windows only). All the PHP
+	processes have to map shared memory into the same address space. This
+	directive allows to manually fix the "Unable to reattach to base address"
+	errors.

+ <summary>The Zend Optimizer+ provides faster PHP execution through opcode caching and optimization.</summary>
+ <description>
+  The Zend Optimizer+ provides faster PHP execution through opcode caching and
+  optimization. It improves PHP performance by storing precompiled script
+  bytecode in the shared memory. This eliminates the stages of reading code from
+  the disk and compiling it on future access. In addition, it applies a few
+  bytecode optimization patterns that make code execution faster.

+/*
+	zend_accel_hash - is a hash table allocated in shared memory and
+	distributed across simultaneously running processes. The hash tables have
+	fixed sizen selected during construction by zend_accel_hash_init(). All the
+	hash entries are preallocated in the 'hash_entries' array. 'num_entries' is
+	initialized by zero and grows when new data is added.
+	zend_accel_hash_update() just takes the next entry from 'hash_entries'
+	array and puts it into appropriate place of 'hash_table'.
+	Hash collisions are resolved by separate chaining with linked lists,
+	however, entries are still taken from the same 'hash_entries' array.
+	'key' and 'data' passed to zend_accel_hash_update() must be already
+	allocated in shared memory. Few keys may be resolved to the same data.
+	using 'indirect' entries, that point to other entries ('data' is actually
+	a pointer to another zend_accel_hash_entry).
+	zend_accel_hash_update() requires exclusive lock, however,
+	zend_accel_hash_find() does not.
