最快线程间数据交换算法,有效避免锁竞争 -- TwoQueues

处理多线程数据共享问题注意的几个要点:

1、锁竞争:尽量减少锁竞争的时间和次数。

2、内存:尽量是使用已分配内存,减少内存分配和释放的次数。尽量是用连续内存,减少共享占用的内存量。

多线程数据交换简单方案A:

定义一个list,再所有操作list的地方进行加锁和解锁。

简单模拟代码:

PGO: Let It Go (PHP)

We can hope that companies like Intel® will come along with a faster processor. (And this does tend to happen every year). Or we can improve our compilers to produce better machine code. Or we can analyze our own code and change it to run more optimally. For PHP, we do all three: We partner with the processor architects to improve the way they execute PHP; we look for changes we can make to the...
