Sorry, I can't supply references, but I read an article recently that
discussed the very issue and several related myths.  According to the
article the L, LTR was actually faster in older (much older) machines,
but in since like the 370/168 the ICM is actually faster.  If it's really
important I could see if I could dig up the article.
