I'd bought one of the first haswell notebooks to play around with tsx. Before I'd time to do so Intel found the tsx bug... I hope to have time to play around with it one I have new hardware (I refuse to do performance development on virtual). But honestly, most remaining performance/scalability problems in pg are more algorithmically caused. So micro optimization, and that's what I'd call tax/hle, aren't likely to biggest bottleneck.
