Chrony uses half the resident size than ntpd (top output).
But more than twice virtual memory
Yes, but as Stefan Seyfried says, that is not relevant, it is not occupy ram chips.
The other output is from "ps", I guess; I don't know there what "SIZE" means, what exact concept. :-?
The SIZE and RSS fields don't count some parts of a process including the page tables, kernel stack, struct thread_info, and struct task_struct. This is usually at least 20 KiB of memory that is always resident. SIZE is the virtual size of the process (code+data+stack).
Ah, it counts virtual size too. Then it is not useful for this comparison. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
