Single data query
About 300000 data. It’s twice as slow to test as mysql. I don’t know where it’s wrong

The network IO problem may be. Check the network. Local

Okay. Check the local network. Hardware resource occupation and so on. What about sockets?

I made a naive mistake. I made 300000 links to redis and made modifications. I can use hgetall 10 times faster and get 15 times faster, but I still feel it’s not ideal. It’s still too slow

If the network overhead is too large each time, you can consider to try redis’s pipelining feature. But note that the server will queue all requests in memory, so do not send too many requests at a time. For details, please refer to this

Is the persistence of redis set? Redis is memory based. MySQL has no comparability with it.
