So this is my favorite theory at this point: The (band-limitted) resampler was 
normally not computing. When VLC triggered resampling it was slower than ti is 
now. The key difference, as Raphaël observed for Android some time ago, is 
that we are now resampling continuously to avoid audible glitches.

There are other theories.

It could affect Windows only or contribs only due to some as yet unknown 
issue. There are however strong suspicions that the problem also affects Linux 
distributions. That theory is very weak.

Or maybe people got used to the workaround in VLC 1.1.8 onward whereby the 
band-limited resampler was disabled due to crashes. Or maybe crappy x86 
processors became more prevalent recently.
