If --startuptime does not fit your needs, you may use the following command:
vim --cmd 'profile start profile.log' \
--cmd 'profile func *' \
--cmd 'profile file *' \
-c 'profdel func *' \
-c 'profdel file *' \
-c 'qa!'
You will get all timings in the profile.log. Table with function timings will be
present at the end of the file, to get per-script timings, use the following
script:

" Open profile.log file in vim first
let timings=[]
g/^SCRIPT/call add(timings, [getline('.')[len('SCRIPT '):],
matchstr(getline(line('.')+1), '^Sourced \zs\d\+')]+map(getline(line('.')+2, line('.')+3),
'matchstr(v:val, ''\d\+\.\d\+$'')'))
enew
call setline('.', ['count total (s) self (s) script']+map(copy(timings),
'printf("%5u %9s %8s %s", v:val[1], v:val[2], v:val[3], v:val[0])'))

This will open a new file containing just the same table as at the end of
profile.log, but 1) for scripts, not for functions, 2) unsorted.
