终端使用ab测试
开启前
在本地 请求10000 并发200 看看处理情况
刚开始不稳定,瞬间并发,可能直接崩溃,要不就是响应时间超级慢,可以都测试几次 取平均值

fishMacBook-Air:~ may$
只想说 开启opcache后 ,性能提升不少
做个比较
就单看第三项
Requests per second: xxx [#/sec] (mean)吞吐量-每秒请求数
Time per request: xxxx [ms] (mean)服务器收到请求，响应页面要花费的时间
Time per request: xxx [ms] (mean, across all concurrent requests)并发的每个请求平均消耗时间
延长的问题
根据自己的需要选择自己需要配置的选项
[opcache]
zend_extension = "/Applications/MAMP/bin/php/php5.6.30/lib/php/extensions/no-debug-non-zts-20131226/opcahe.so"
; Zend Optimizer + 的开关, 关闭时代码不再优化.
opcache.enable=1
; Determines if Zend OPCache is enabled for the CLI version of PHP
opcache.enable_cli=1
; Zend Optimizer + 共享内存的大小, 总共能够存储多少预编译的 PHP 代码(单位:MB)
; 推荐 128
opcache.memory_consumption=64
; Zend Optimizer + 暂存池中字符串的占内存总量.(单位:MB)
; 推荐 8
opcache.interned_strings_buffer=4
; 最大缓存的文件数目 200 到 100000 之间
; 推荐 4000
opcache.max_accelerated_files=2000
; 内存“浪费”达到此值对应的百分比,就会发起一个重启调度.
opcache.max_wasted_percentage=5
; 开启这条指令, Zend Optimizer + 会自动将当前工作目录的名字追加到脚本键上,
; 以此消除同名文件间的键值命名冲突.关闭这条指令会提升性能,
; 但是会对已存在的应用造成破坏.
opcache.use_cwd=0
; 开启文件时间戳验证
opcache.validate_timestamps=1
; 2s检查一次文件更新 注意:0是一直检查不是关闭
; 推荐 60
opcache.revalidate_freq=2
; 允许或禁止在 include_path 中进行文件搜索的优化
;opcache.revalidate_path=0
; 是否保存文件/函数的注释 如果apigen、Doctrine、 ZF2、 PHPUnit需要文件注释
; 推荐 0
opcache.save_comments=1
; 是否加载文件/函数的注释
;opcache.load_comments=1
; 打开快速关闭, 打开这个在PHP Request Shutdown的时候会收内存的速度会提高
; 推荐 1
opcache.fast_shutdown=1
;允许覆盖文件存在（file_exists等）的优化特性。
;opcache.enable_file_override=0
; 定义启动多少个优化过程
;opcache.optimization_level=0xffffffff
; 启用此Hack可以暂时性的解决”can’t redeclare class”错误.
;opcache.inherited_hack=1
; 启用此Hack可以暂时性的解决”can’t redeclare class”错误.
;opcache.dups_fix=0
; 设置不缓存的黑名单
; 不缓存指定目录下cache_开头的PHP文件. /png/www/example.com/public_html/cache/cache_
;opcache.blacklist_filename=
; 通过文件大小屏除大文件的缓存.默认情况下所有的文件都会被缓存.
;opcache.max_file_size=0
; 每 N 次请求检查一次缓存校验.默认值0表示检查被禁用了.
; 由于计算校验值有损性能,这个指令应当紧紧在开发调试的时候开启.
;opcache.consistency_checks=0
; 从缓存不被访问后,等待多久后(单位为秒)调度重启
;opcache.force_restart_timeout=180
; 错误日志文件名.留空表示使用标准错误输出(stderr).
;opcache.error_log=
; 将错误信息写入到服务器(Apache等)日志
;opcache.log_verbosity_level=1
; 内存共享的首选后台.留空则是让系统选择.
;opcache.preferred_memory_model=
; 防止共享内存在脚本执行期间被意外写入, 仅用于内部调试.
;opcache.protect_memory=0由于我使用的是mamp环境 nginx+mysql+php
php5.6版本
我使用的是默认的配置
这只是在本地测试,end opcache会自动在内存中缓存预先编译好的php字节码，如果缓存了某个文件的字节码，就执行对应的字节码
因为PHP是弱类型语言,不能直接被机器识别,需要 zend 引擎 处理,经过词法分析 语法分析,处理成opcode(operator code)
顺便说一下PHP7中增加了抽象语法树的概念.
再来看
开启opcache前后
开启未测试前
cache hits 命中数 0
cache misses 未命中数 35
使用内存12583384
开启后测试
cache hits 命中数 34326
cache misses 未命中数 54
使用内存13610472b
浏览器访问方面 我们可以对比看到
未开启时 平均响应时间在 94-102 前几次访问140ms左右
开启后平均响应时间在27-34ms
