I'd start from looking on the SSD usage and latency with `gstat -I 1s -pod` and may be CPU usage in `top -SHIz`. Also according to ".eli" in the device name, I suppo= se it is encrypted. So I'd try it without encryption for comparison or checked that you have it accelerated. --=20 You are receiving this mail because: You are the assignee for the bug.=
