New submission from Pigmej <jedrzej.nowak at codernity.com>:
See Attached code.
Script outputs:
- pypy 1.9:
root at ci:/tmp# pypy builder.py
time 1715.36743188
process size 168648 kb
- cpython 2.7.3:
root at ci:/tmp# python builder.py
time 0.507338047028
process size 31668 kb
Also pypy used 100% cpu during whole process.
As I can understand slow pypy with strings, following behaviour is really weird for me.
That part of code is from bigger context, so it might look a bit weird.
