i ran this oneliner sequence. it was a (poor) attempt to force push ram empty. it mostly got empty. but. i think i have a problem here. do you also see problem here? i have 532.07 mb of kernel memory going somewhere. i won't be looking if it doesn't get slower or "overflow" in rare cases. is that a zfs write cache? note that this is on 13.5-RELEASE-p3, currently no other releases, stables or currents where i can perform same tests as a comparison, nor any more powerful systems. i'm reading here that zfs can't give ram back if it's middle of "something". unsure what to think
