DDR4 or DDR5 setup for cephfs Server

Hi,

Has anyone here done benchmarks comparing cephfs performance between DDR4 and DDR5?
I’m currently putting together a configuration for a new Cehp server for my cluster, but I’m not sure if the extra cost for DDR5 is worth it.
The previous servers all still have DDR4, but I can then move the MDS server to the new server if the performance is significantly higher.

Many thanks in advance for your answers

Not done any testing but from experience I expect the storage and network latency to overshadow any impact from memory, assuming we are talking about the same amount of memory.

Hi,
thanks for your answer.
Yes we are talking about the same amount of memory.
