Hello, What's the default granularity with swapping on recent -current on arm64? ie. whats the smallest size of data that is swapped out. 1k? 4k? Where can I find this info? Can it be set/tuned? How to see what it currently is? I'd like to set it to 32k if possible. Read performance on this disk for swap tops out at 60MB/s with a 32k block size. For bs=512 it's 1349 kB/s For bs=4k it's 11MB/s context: the thing I'm trying to work around is poor swap performance on this arch/hardware. --
