redis 速度有那么快吗？

Question

                Jedis j = new Jedis("192.168.1.110");
		Long a = System.currentTimeMillis();
		for (int i = 0; i < 10000; i++) {
			j.get("foo");
		}
		System.out.println(System.currentTimeMillis() - a);
		j.disconnect();

输出：

 5896

楼上高见，建议多看jedis官网

Answer 3

Caused by: java.net.SocketTimeoutException: Read timed out

Answer 4

每秒不到两千，试试并发访问呢?

Answer 5

其实redis里面有个工具直接可以benchmark啊，何苦java呢

Answer 6

回复
哈哈，最主要是JAVA程序里面要用啊。水平限制住了。

Answer 7

回复
我的小本子，8万左右的QPS啊，轻松实现

Answer 8

回复
那你的机子真好，不知道咋回事，连虚拟机里面的linux，还有timeout··

Answer 9

直接用异步客户端，lettuce

Answer 12

内存数据库, rdb和aof只是拿来做持久化的...能不快么...

某世界级XX站全线采用redis后追加服务器不是因为出现性能负载, 而是因为redis跑满G口网卡了...

Answer 14

如果你要做测试，你最好用下面的方式来使用Jedis：

JedisPoolConfig config = new JedisPoolConfig();

JedisPool jedisPool = new JedisPool(config, host, port, TIMEOUT);

Jedis jedis = jedisPool.getResource();

jedis.get(“foo”);

jedisPool.returnResource(jedis).

建议你再多看看网上的用法。你那种用法不是跑performance的。

当然网络环境差的话，用什么都是一样的结果。
