Performance degeneration with time?

Hi Everyone, i noticed a pattern when hosting solana rpc node (not full validator). After some time perfrormance degrates to a point where it's no longer possible for the node to timely process new data, so it starts lagging more and more and is never able to catch up again. Datadirs needs to be cleaned-up, new snapshot downloaded and the node needs to be started again. Not sure what could be the case maybe it's DB or RAM fragmentation.

EPYC 73F3 x2 1.5TB Ram solana-validator 1.18.18

Proposed solution: Any possibility to run some cleanup / defragment on a working node from time to time, or maybe my config is incorrect?
