Why is Redis so slow?

For instance a benchmark setting 4 KB strings in Redis at 100000 q/s, would actually consume 3.2 Gbit/s of bandwidth and probably fit within a 10 Gbit/s link, but not a 1 Gbit/s one. In many real world scenarios, Redis throughput is limited by the network well before being limited by the CPU.

Is Redis fast?

The general answer is that Redis 10 - 30% faster when the data set fits within working memory of a single machine. Once that amount of data is exceeded, Redis fails. Mongo will slow down at an amount which depends on the type of load.

Is there anything faster than Redis?

Redis vs MongoDB Speed This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.

Is Redis low latency?

Usually Redis processing time is extremely low, in the sub microsecond range, but there are certain conditions leading to higher latency figures.

Why is Redis so slow?

Huge number of simultaneous sessions (>30000) Too many connection operations per second (Redis is not a webserver, connections are supposed to be permanent, not transient). Too many roundtrips generated by the client application (no pipelining or aggregated command usage)
