I have to agree. The only time speed has been an issue with large
directories and ls for me was when I was accessing an NFS mount.

I did the same test with 100,000 files on a FreeBSD box and got the
following results:

$ ~/tmp> time ls > /dev/null

real 0m1.578s
user 0m0.180s
sys 0m1.368s
$ ~/tmp> time ls -l > /dev/null

real 0m1.975s
user 0m0.597s
sys 0m1.359s
