Alright, I ran a few benchmarks myself.  In rigorous mode regex_v8 has the same performance on my 2013 Macbook Pro and an 8-years old i7 CPU (Linux).

Here're results of "perf.py -b raytrace,spectral_norm,meteor_contest,nbody ../cpython/python.exe ../cpython-git/python.exe -r"


fastint5:

### nbody ###
Min: 0.227683 -> 0.197046: 1.16x faster
Avg: 0.229366 -> 0.198889: 1.15x faster
Significant (t=137.31)
Stddev: 0.00170 -> 0.00142: 1.1977x smaller

### spectral_norm ###
Min: 0.296840 -> 0.262279: 1.13x faster
Avg: 0.299616 -> 0.265387: 1.13x faster
Significant (t=74.52)
Stddev: 0.00331 -> 0.00319: 1.0382x smaller

The following not significant results are hidden, use -v to show them:
meteor_contest, raytrace.
