Redis对Hget和HSet命令的基准测试 [英] Redis benchmarking for hget and hset commands

问题描述

我找不到带redis的HGET，HSET(哈希表命令)基准测试的示例.关于此的任何示例或资源都将是有用的.

I could not find an example for bench marking of HGET , HSET (hash table commands) with redis. Any example or resource will be useful regarding this.

推荐答案

我刚刚意识到 redis-benchmark 命令没有对 hSet 和 hGet 命令.(我正在使用v2.8.5)

I just realized redis-benchmark command does not benchmark hSet and hGet commands. (I'm using v2.8.5)

您可以做的是编写一个小程序来对性能进行基准测试:

What you could do is write a small program to benchmark the performance:

<?php

$redis = new Redis();
$redis->pconnect("127.0.0.1");

$count = 10000;

$start_t = microtime(true);
for ($i = 1; $i < $count; $i++) {
    $redis->hSet("h{$i}", 'f', $i);
}
$end_t = microtime(true);

echo "Time taken for hSet = " . round(1000 * ($end_t - $start_t)) . "ms (for " . number_format($count) . " keys)\n";

$start_t = microtime(true);
$pipeline1 = $redis->pipeline();
for ($i = 1; $i < $count; $i++) {
    $pipeline1->hSet("h{$i}", 'f', $i);
}
$result2 = $pipeline1->exec();
$end_t = microtime(true);

echo "Time taken for hSet (bulk) = " . round(1000 * ($end_t - $start_t)) . "ms (for " . number_format($count) . " keys)\n";

$start_t = microtime(true);
for ($i = 1; $i < $count; $i++) {
    $redis->hGet("h{$i}", 'f');
}
$end_t = microtime(true);

echo "Time taken for hGet = " . round(1000 * ($end_t - $start_t)) . "ms (for " . number_format($count) . " keys)\n";

$start_t = microtime(true);
$pipeline2 = $redis->pipeline();
for ($i = 1; $i < $count; $i++) {
    $pipeline2->hGet("h{$i}", 'f');
}
$result2 = $pipeline2->exec();
$end_t = microtime(true);

echo "Time taken for hGet (bulk) = " . round(1000 * ($end_t - $start_t)) . "ms (for " . number_format($count) . " keys)\n";


$start_t = microtime(true);
$pipeline3 = $redis->pipeline();
for ($i = 1; $i < $count; $i++) {
    $pipeline3->hDel("h{$i}", 'f');
}
$result3 = $pipeline3->exec();
$end_t = microtime(true);

echo "Time taken for hDel (bulk) = " . round(1000 * ($end_t - $start_t)) . "ms (for " . number_format($count) . " keys)\n";

在我的测试服务器上，结果如下:

On my test server, results are as follows:

$ php redis/benchmark_redis.phphSet花费的时间= 557ms(用于10,000个键)hSet(批量)= 51ms(用于10,000个键)所花费的时间hGet花费的时间= 483ms(用于10,000个密钥)hGet(批量)花费的时间= 43ms(用于10,000个密钥)hDel(批量)花费的时间= 49ms(用于10,000个键)
