One of my client M2 store is using Redis for session and cache storage. On inspecting the New Relic, have noticed that HGET is consuming hell lot of time Redis HGET

Redis Configuration:

  • Local Redis connected with TCP
  • Setting: maxmemory-policy allkeys-lru

How do you guys optimize the Redis (single instance) for your M2 store?

Magento >= 2.3.5 have a preload functionality that allows to load multiple keys by one request.

See https://devdocs.magento.com/guides/v2.3/config-guide/redis/redis-pg-cache.html#redis-preload-feature for more details

Works especially well with two level cache https://devdocs.magento.com/guides/v2.3/config-guide/cache/two-level-cache.html

  • That's a good point but unfortunately store is operating on version < 2.4.0

  • You can back port cache adapter to your version (just copy/past ;)

  • You mean just to udpate the Redis module from M 2.4?
