| Jack asked for this report: """ MacPython uses it. At the time it was put in it caused a 15% increase in Pystones because dictionary entries were aligned in cache lines. But: this was in the PPC 601 and 604 era, I must say that I've never tested whether it made any difference on G3 and G4. Put in a bug report in my name, and one day I'll get around to testing whether it still makes a difference on current hardware and rip it out if it doesn't. """ | ||

| Logged In: YES user_id=45365 As MacPython normally uses the standard MSL malloc nowadays (and will probably use pymalloc in the future) the benefit of USE_CACHE_ALIGNED has disappeared. I've removed it. | ||
