100000ii

Prompted by a challenge here:

https://fivethirtyeight.com/features/pirates-monkeys-and-coconuts-oh-my/

(Near the bottom of the page, in the answers to the previous challenge
dealing with editors.)

I tried inserting a million letter "i"s into a new buffer with vim. Oh,
how insanely slow it was. I hit control-C after 20ish seconds and it was
up to about 30,000 letters inserted. I tried two different builds of vim.

Then, for comparison, I used nvi and elvis. Nvi does it too fast to measure by
wall clock. Elvis was under 5 seconds.

vim: VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Nov 24 2016 16:44:48)
(This version is the package one for my Ubuntu release.)


vim: VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Mar 13 2018 17:19:45)
nvi: Version (1.81.6-2013-11-20nb3) The CSRG, University of California, Berkeley.
elvis: elvis 2.2.0
(These three were all tried on NetBSD, the Vim and Elvis compiled from source,
the Nvi the system /usr/bin/vi.)

I don't think blinding fast is entirely necessary, but not even half-way
there in 20 seconds is Not Good.
