> Why is this important to you? I would not say that it's a useless use case. It may be a rare case but it can happen. When it happens, insertion can take so much time that user may have to press CTRL-C. I recall that this was discussed earlier but I can't find the thread. It's probably not simple to fix so it has not been fixed yet. Performance looks currently quadratic since time is multiplied by ~ 4 each time we double the insert count: $ /usr/bin/time ./vim --clean -c 'norm 5000ix' -c 'q!' 0.13user 0.00system 0:00.13elapsed 99%CPU (0avgtext+0avgdata 17532maxresident)k 0inputs+8outputs (0major+1292minor)pagefaults 0swaps $ /usr/bin/time ./vim --clean -c 'norm 10000ix' -c 'q!' 0.72user 0.00system 0:00.73elapsed 99%CPU (0avgtext+0avgdata 17684maxresident)k 0inputs+8outputs (0major+1301minor)pagefaults 0swaps $ /usr/bin/time ./vim --clean -c 'norm 20000ix' -c 'q!' 3.37user 0.00system 0:03.37elapsed 99%CPU (0avgtext+0avgdata 17744maxresident)k 0inputs+8outputs (0major+1311minor)pagefaults 0swaps $ /usr/bin/time ./vim --clean -c 'norm 40000ix' -c 'q!' 14.05user 0.00system 0:14.06elapsed 99%CPU (0avgtext+0avgdata 17592maxresident)k 0inputs+8outputs (0major+1318minor)pagefaults 0swaps In theory, it could be done quickly in O(n).
