RE: Periodic several second freezes with Raspberry Pi 3
Deadline is a popular option among flash drives. CFQ is typically the default used with moving-parts disks.
If that affects it, it definitely indicates this is IO latency related. Are you using a cso or iso? How much memory does the device have? Could it be swapping - do you see swap usage? Do pis come by default with zram configured, or do they use SD card swap, or no swap at all? -[Unknown] |
