php yac使用,php yac简单压测
个人PC！4G内存，双核CPU
1、即写又读压测
$yac= new Yac();
for($i = 0; $i<1000; $i++) {
$key= "xxx". $i;
$value= str_repeat("x", $i);
if(!$yac->set($key, $value)) {
var_dump("write" . $i);
}
if($value != ($new = $yac->get($key))) {
var_dump("read" . $i);
}
}
var_dump($i);

2、只写压测
$yac= new Yac();
for($i = 0; $i<1000; $i++) {
$key= "xxx". $i;
$value= str_repeat("x", $i);
var_dump($yac->set($key,$value));
}
var_dump($i);

3、只读压测
$yac= new Yac();
for($i = 0; $i<1000; $i++) {
$key= "xxx". $i;
$value= str_repeat("x", $i);
var_dump($yac->get($key));
}
var_dump($i);

总结：
1、为什么写比读还快呢，性能还好呢？
2、1000个KEY有4个KEY的失败，返回null
