*This is the same laptop that was used to compute 116,580,041 digits in December 2006.
116 million digits was believed to be a new world record at the time, but it was later revealed that S. Kondo and S. Pagliarulo already had 2 billion digits but had yet to announce it.
That computation of 116 million digits took 38.5 hours using my old Java library. y-cruncher matched it in a mere 4 hours and 13 minutes on the same laptop.
On Nagisa, y-cruncher can do it in 17 minutes. That's a 136x improvement from two years ago!
