神啊！

以前用的主题atahualpa 2.21版本，现在都升级到3.4.4啦！嗯，接着用。

虽说拿到本后大半年就没摸过车，今天办完手续直接就开着上路啦，保险都没有生效，真担心刮蹭啥的。刚出来找加油站就被后面车嘀个不停，而且还发现安全带都没有系上。。。加完油后赶紧把实习标拿出来贴上，再上路，嘀声少了不少，啊哈哈

从西南三环，到北三环，然后走八达岭高速辅路，车真多啊！早上7点出门，车开到家正好3点半，估计开了估计有2个小时吧。

现在还在使劲看说明书，嗯

Zend Optimizer 配置如下： [Zend] zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3 zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3 zend_optimizer.version=3.3.3 zend_optimizer.optimization_level=1023 zend_optimizer.enable_loader = 0 zend_optimizer.disable_licensing=1 zend_optimizer.obfuscation_level_support=0 zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so

With default install of ZendOptimizer-3.3, SELinux enabled, [...]]]> 以前必须吧SELinux关了才能用ZendOptimizer，昨天研究了一下，终于让ZendOptimizer和SELinux能一起工作了~~

Zend Optimizer 配置如下：
[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3
zend_optimizer.version=3.3.3
zend_optimizer.optimization_level=1023
zend_optimizer.enable_loader = 0
zend_optimizer.disable_licensing=1
zend_optimizer.obfuscation_level_support=0
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so

With default install of ZendOptimizer-3.3, SELinux enabled, ZendOptimizer can’t be load.

php -v:

How to enable ZendOptimizer work with SELinux:

1. 1. Change context of ZendOptimizer.so and ZendExtensionManager.so

2. if your php compiled with threadsafe, change the xxx_TS.so instead.

chcon -t textrel_shlib_t ‘/usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so’
semanage fcontext -a -t textrel_shlib_t ‘/usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so’

chcon -t textrel_shlib_t ‘/usr/local/Zend/lib/ZendExtensionManager.so’
semanage fcontext -a -t textrel_shlib_t ‘/usr/local/Zend/lib/ZendExtensionManager.so’

1. 2. vim zend_optimizer.te, copy the following content

module zend_optimizer 1.0;

require {
    type httpd_t;
    class process { execstack execmem execheap };
}
#============= httpd_t ==============
allow httpd_t self:process { execstack execmem execheap };

1. 3. compile :

   checkmodule -M -m -o zend_optimizer.mod zend_optimizer.te

2. 4. create policy package:

semodule_package -o zend_optimizer.pp -m zend_optimizer.mod

1. 5. install module:

   semodule -i zend_optimizer.pp

service httpd restart

建了一个1G的ramdisk，高位内存768M，不够的部分在windows能识别里面分配，然后把Temp文件夹和IE临时文件都放到ramdisk里面了。用硬盘工具测试了一下，ramdisk的读取速度平均在2.8G/s左右，最高达到了3.6G/s~
