So I enabled swapfile on a different volume with higher priority instead. Make sure swapfile priority is higher than of other swaps. Configure swapfile setup on system boot. $ sudo truncate -s 2G /volumeX/swapfile $ sudo mkswap /volumeX/swapfile $ sudo swapon -p 9 /volumeX/swapfile $ swapon --show

Hi all! Has anyone ever tried configuring md1/swap partition with RAID0 instead of default RAID1? I have terrible QD and latency using swap. My Synology NAS has small built-in memory so it often pages in and out. My theory is that 4 HDDs in RAID0 (instead of RAID1) for swap partition should give slightly better random read and writes. Any experience out there please?

Sorry for digging out old post, but I am also looking for this since I have terrible QD and latency on my md1 (swap) partition. Have you managed to archive that?

Может кому поможет если нагуглят. У Synology кастомный htop, который показывает полезные SYNOCPU и SYNOIO. Не помешает запустить htop чтобы посмотреть кто не справляется с задачей. В моей практике было, что SYNOCPU 1 или 2, а SYNOIO аж от 15 до 19. iostat -x показывал average queue depth 30 на md1 (swap) и меньше на RAID томе. Соответственно диски просто не справлялись и вся система благополучно из-за них висела.
