To get an accurate reading of the time spent by the shell itself, you
should compare a command that generates the list of files and then
throws it away; e.g.

    time zsh -fc '/bin/true */*/*.ebuild'

There's really no way to get timings of the glob without also adding
the shell startup time, so this may be a little off (hence -f to try
to skip as much startup as possible).

To make the zsh time output look like bash's,


There are a whole lot of other possible values you can put in TIMEFMT in
zsh to get more details about where it might be taking extra.
