AFAIK, the page size can be different for different processes, so I guess we'd need to find the page size per process in something like /proc/<pid>/status? Is that the right way to do it? I'm not on a GNU/Linux machine right now so I can't check.

The processes that end up in that list have memory footprint so small
that top ends up showing percentage memory as 0. I modified the snippet
to obtain 5 processes started by firefox:

The percentage memory values in top for these processes are 12.1 0.2 4.0
0.4 and 4.2 so 4 times those returned by proced.
> Thanks in advance.
From discussion with Eli at the help-gnu-emacs thread I think there is
some hard coded assumption about 4KB page size in sysdep.c. E.g. here at
line 3741
pmem = 4.0 * 100 * rss / procfs_get_total_memory ();
Thanks,

1. What is the output of running this command?
grep MemTotal /proc/meminfo
Does that value seem right? Does that file make sense in general?
2. Copy this to a buffer somewhere, put point after the last
parenthesis, and press `C-u C-x C-e':
(pp (mapcar #'process-attributes
(seq-take (list-system-processes) 5)))
Please post the result back here.
Could you also tell us which values in the resulting list are wrong
(a.k.a. "different from top")?
Thanks in advance.

They provide a kernel with 16KB page size [2]. This causes proced to show incorrect values for percentage memory (other memory related attributes might also be affected). E.g. comparing with top I see that value reported by proced is a quarter of that related by top.
