Are you talking about dbcache? The default value for dbcache is 100mb but it should depend on your memory RAM size and I use it to speed up the syncing process on the Bitcoin core whether it is a pruned or non-pruned node.

Plus why use v22.0 that's old version of Bitcoin core the current recent one is 27.1 you should download the latest one if you don't want to experience some syncing issues.
