Are you looking at the same benchmarks and charts that I am?

http://antoniocangiano.com/category/ruby-benchmark-suite/

This clearly shows that 1.9.1 is consistently and measurably faster than 1.8 in nearly every benchmark. My own experience proves this out too. 

I am a recent convert to 1.9.1 after I discovered that it ran *all* of my scripts at least 50% faster than 1.8.7. Between 1.9.1 and JRuby I am loving my ruby performance lately. I am also tracking Rubinius closely; it is very fast but its performance is less consistent than MRI and JRuby so far.
