Between 1.7.12.x series and v2.1.4, there are more than two years' worth of changes, so it is unreasonable for anybody to expect that such a question can be answered in a meaningful way.

Have you tried more recent versions yet? 2.1.x series is over a year old, and I am reasonably sure there have been tons of "earlier we did X for correctness, which unfortunately made things slower, and this ensures the same correctness in a different way that is much more performant" fixes since then.
