Prashant's Perceptions

Ruby 1.9 very first impression

Program: ruby -e 'require "benchmark"; p Benchmark.realtime { a=0;1000000.times {a = a + 1}; p a} '

On a machine running OpenSolaris on AMD Opteron. The timings are:

x64 Ruby 1.8.6: 1.31seconds
x64 Ruby 1.9: 0.198 seconds

I'll want to run programs that aren't as simplistic, of course, but still, wow! that's an 84% improvement for this loopy.
