Question: How fast is Redis?

Answer

Redis is known for its speed and high performance. It is an in-memory data structure store that can perform millions of operations per second. Redis achieves this by using an optimized, single-threaded architecture and by keeping all data in memory.

Here are some benchmarks that demonstrate Redis's speed:

• Redis can do around 110,000 SETs per second on a entry-level laptop.
  CODE_BLOCK_PLACEHOLDER_0
• Redis can handle up to 1 million SETs per second on a powerful server.
  CODE_BLOCK_PLACEHOLDER_1
• Redis can fetch 81,000 values per second with pipelining enabled.
  CODE_BLOCK_PLACEHOLDER_2
• Redis can process more than 1 million transactions per second with multi-exec commands.
  CODE_BLOCK_PLACEHOLDER_3

It's worth noting that these benchmarks were performed on a local machine, and your mileage may vary depending on your hardware, network topology, and workload. However, the benchmarks provide a good indication of Redis's performance.
