【中文标题】用于 hget 和 hset 命令的 Redis 基准测试【英文标题】:Redis benchmarking for hget and hset commands 【发布时间】:2014-05-14 09:22:57 【问题描述】:我找不到使用 redis 对 HGET 、 HSET (哈希表命令)进行基准测试的示例。任何示例或资源都会对此有用。
【问题讨论】:
【参考方案1】:我刚刚意识到redis-benchmark
命令不能对hSet
和hGet
命令进行基准测试。 (我使用的是 v2.8.5)
你可以做的是编写一个小程序来对性能进行基准测试:
<?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:
$ php redis/benchmark_redis.php
Time taken for hSet = 557ms (for 10,000 keys)
Time taken for hSet (bulk) = 51ms (for 10,000 keys)
Time taken for hGet = 483ms (for 10,000 keys)
Time taken for hGet (bulk) = 43ms (for 10,000 keys)
Time taken for hDel (bulk) = 49ms (for 10,000 keys)
【讨论】:
【参考方案2】:我用的是3.0.2,下面的命令可以对hset redisredis-benchmark -h 192.168.22.58 -p 6379 -d 100 -c 10 -n 1000000 hset myhash rand_int rand_string
进行基准测试
【讨论】:
-d
开关在指定命令时无效 - 它仅用于 redis-benchmark
