Editors' speed on opening big files

While playing with different editors (namely vim and sam) I tried to time how long some common editors take to open a big file (~140Mb).

Here are the results:

editor	real	user	sys
ed	4.866s	3.440s	3.440s
vim	2.086s	0.836s	0.232s
nano	16.264s	15.361s	0.172s
sam	way too long

Then, for curiosity, I timed less with and without (-n) line numbering:

less	3.552s	0.200s	0.072s
less -n	0.182s	0.016s	0.016s

Not sure what to do with these numbers, yet…
