Is Redis faster than memory?

What's the advantage of Redis vs using memory?

Redis is an in-memory but persistent on disk database, so it represents a different trade off where very high write and read speed is achieved with the limitation of data sets that can't be larger than memory.

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.

Does Redis use a lot of memory?

Redis compiled with 32 bit target uses a lot less memory per key, since pointers are small, but such an instance will be limited to 4 GB of maximum memory usage. To compile Redis as 32 bit binary use make 32bit.

Why is Redis faster?

The reasons for the high performance of redis are as follows: Memory storage: redis uses memory (in memory) storage, without disk IO overhead. Single thread implementation: redis uses a single thread to process requests, avoiding the cost of thread switching and lock resource contention between multiple threads.
