Redis对Hget和HSet命令的基准测试

我只是意识到

redis-benchmark

hSet

hGet

您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)
