We see a much cleaner syntax for defining these functions, which can be optimized for performance by opcode caches.
我们看到了定义这些函数的更规则的语法，这可以通过操作码缓存来优化性能。
Unlike APC and Wincache, it is only an opcode cache and optimizer, so it does not contain the user cache components.
不同于APC和Wincache，它仅是一个操作码缓存和优化器，因此它不包含用户缓存组件。
If a serious error occurs, for example, an invalid opcode, the SPU is stopped and an interrupt is delivered to the ppe.
如果发生了一个非常严重的错误，例如一个无效的操作码，那么SPU就会停止，并向PPE发送一个中断。
The easiest thing to boost performance of any PHP application (the "p" in LAMP, of course) is to take advantage of an opcode cache.
提高任何PHP应用程序(当然是LAMP中的“P”)的性能的最简单方式是利用一个操作码缓存。
If the program has more than one occurrence of the opcode, try to find the sequence printed by the handler code in the dump file.
如果这个程序中一条操作码出现了多次，请尝试在dump文件中寻找处理程序代码所打印的序列。
In contrast, concatenating a string is pretty much just a case of running a single opcode to append a string variable to an existing string variable.
相反，连接字符串操作非常简单，只是运行一个操作码，将一个字符串变量附加到一个现有的字符串变量中即可。
When a PHP script is requested, PHP reads the script and compiles it into what's called Zend opcode, a binary representation of the code to be executed.
请求一个php脚本时，php会读取该脚本，并将其编译为Zend操作码，这是要执行的代码的一种二进制表示形式。
Hardware transient faults can cause control flow errors and corrupt the normal execution process by altering the operand and opcode of instructions.
硬件瞬时故障可以通过修改指令操作码和操作数的方式引发控制流错误，破坏程序的正常执行。
You may as well just map the opcode "DELETE" to whatever function is appropriate for deletion in your environment and language, to take that example.
为实现示例，您同样可以将操作代码“DELETE”映射到您的环境和语言中任何适当的用于删除的函数。
An opcode cache — and an opcode optimizer, which is often provided in the same package — is a dirt-cheap technique to hasten the responsiveness of your site.
操作码缓存——以及一个操作码优化器，通常由相同的包提供——是一种加快站点响应的低成本技术。
As expected, the program has received a SIGILL (signal number 4) with an si code of 5, which is set when a privileged opcode is executed by a user-space program.
正如我们期望的一样，这个程序会接收到一个SIGILL(信号编号为4)信号，其si代码为5，这是在用户空间的程序执行特权操作时产生的。
Each instruction on the PowerPC is exactly 32 bits long, with the instruction's opcode (the code telling the processor which instruction it is) taking the first six bits.
PowerPC上的每条指令都正好是32位长，指令的opcode(操作符，告诉处理器这条指令是什么的代码)占据了前6位。
It is still a good idea to keep in mind since not all opcode optimizers perform this optimization and there are plenty of ISPs and servers running without an opcode optimizer.
牢记这个优化处理不失为一个好主意，因为并不是所有的指令优化器都会做同样的优化处理，并且存在大量没有装配指令优化器的互联网服务提供商(ISPs)和服务器。
For any website I work with, it's the one thing I make sure is present, since the performance impact is huge (many times with response times half of what they are without an opcode cache).
对于我使用的任何网站，它是我确保存在的一项内容，因为性能影响很大（很多时候有了操作码缓存，响应时间可减少一半）。
One way of debugging this failure is to do an object dump of the executable and save it in a file, then search for the failed instruction (in this case, the failed opcode is 98080000).
调试这个问题的一种方法是对这个可执行程序执行objdump命令，并将其结果保存到一个文件中；然后查找出错的指令(在本例中，出错的操作码是98080000)。
Control circuitry interprets the opcode and executes the instruction by sending out the appropriate control signals to cause data to be moved or an operation to be performed by the ALU.
控制电路翻译操作码，并且通过发送相应的控制信号来执行指令。这些信号控制数据的传送和ALU操作的执行。
We looked at techniques not only at the PHP level, by leveraging an opcode cache and optimizing the PHP configuration, but also looked at optimizing your database design for proper indexing.
我们不仅通过利用一个操作码缓存和优化PHP配置探究了php级别的技术，而且探究了如何优化您的数据库设计来实现合理的索引编制。
While implementing an opcode cache is a big bang for performance improvement, there are a number of other tweaks you can do to optimize your PHP setup, based upon the settings in your php.ini file.
虽然实现操作码缓存是性能改进的一大创举，不过也有大量其他优化选项可供您基于php.ini 文件中的设置优化您的 PHP设置。
