I'm not sure what you mean by 'test set' but how about this:
Launch gcmd --debug=n (or better =dfgplmn) from a terminal, or catch the
xsession stdout debug log, like (on Debian)
tail -F ~/.xsession-errors
Start 'top' on another terminal. Don't use a resource consuming graphical
system monitor.
Create a 100 MB file,
dd if=/dev/zero of=/tmp/100MB count=200000
then copy it according to Assafs description, both gcmd panes showing
the same dir. Note the result. Then stop FAM or gamin (or deinstall) for
a second run. (Can we stop gnome-vfs from using libfam monitors ?)
To compare the results with other machines, some basic infos could be
helpful:
free -m
grep '\(^(--\|WW\|RAM:\)' /var/log/Xorg.0.log
dmidecode # or cpuid
uname -a
zgrep '\(CONFIG_HZ\|PREEMPT\)' /proc/config.gz
On old machines with less video power, a high CPU load can be caused
by X working on filelist widget updates, rather than by the filemanager or
FS monitors itself. Which can probably be tested by copying on shell:
cd /tmp
/usr/bin/time --verbose 100MB 100MBcopy
(you can use the shell command 'time' as well but it lacks a 'verbose' mode)
Here's my old machnine:
/tmp mi: /usr/bin/time --verbose cp -av 100MB 100MBcopy
`100MB' -> `100MBcopy'
Command being timed: "cp -av 100MB 100MBcopy"
User time (seconds): 0.10
System time (seconds): 3.96
Percent of CPU this job got: 40%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:09.95

The CPU percentage of gcmd is nearly the same, a running FAM is (far) below 5%.
That example was, btw, with lots of apps open and even a running update,
so a typical desktop situation ;)
Here's the hardware specs: (script log, trimmed down)
