    Hello,

    We're currently using the Redis caching (backend + guest page + css ) on xenforo 2.1.4 and compression enabled with gzip.

    However, i see that lz4 compression has more advantages than gzip generally but what about in redis?

    Anyone have experience for that? Thanks

    Just stick with gzip :)

    Max compression gzip or brotli server-side to Redis will definitely reduce your bill however max compression will probably not work to minimize latency. There are a lot of things which can be done to make more efficient use of Redis. Refer to this slide presentation.

    I though ideal choice is gzip #1 (comp level) then. (especially for xenforo forum caching)

    There are very good arguments for implementing compression but the more highly compressed the data the more latency will be added for the overhead of processing. It may be more beneficial to use a different form of storage if you are generating too much in-memory data due to cost limitations. Or it may be wiser to look at how you can optimize your code as well as your Redis schema to minimize the amount of data that must be stored in memory. It isn't possible for me to say but I also don't think that using gzip level 1 is going to tank anyone's product either.
