Better to reinstall may be. I dont rule out that 32bit cant be faster but we need to measure it > The machine running 64 bit 11.04 was tested with 32 bit 11.04 > using an external disk (connected through e-SATA) and results > were very close to the numbers for the other 32 bit machine > > I didn't save those numbers but I think that is good enough > to draw the conclusion that adding JIT for 64 bit (PyPy?) will reduce build > time significantly. Thats what I am interested in. If pypy would make it faster than we could recommend it.
