      Substantial performance gains for PyPy. · add499ab
      Jason Madden authored
      First, eliminate the use of the RingWrapper object and always delete
      by index. It was only necessary to allow use of ring.remove(). This
      had some performance impact, but mostly saves memory.
      
      Second, eliminate the use of `enumerate` in the hot mru() path. This was the big performance win.
      
      Current results:

      Optimize the _p_accessed code path in pure-python for substantial performance improvements. · 6fa457df
      Jason Madden authored
      Some very minor tweaks to avoid going through the __getattribute__ path so much have large consequences for `zodbshootout`:
      
        Results show objects written or read per second. Best of 3. (before/after on pypy2.5.1)

      Jason Madden authored
      The python _p_activate does state management like the C version does: set to changed during jar.setstate to prevent objects that set attributes in their __setstate__ from being registered with the jar, and unconditionally mark the object as saved when finished. This fixes problems with BTrees and DB churn, among other things. Test this.
