[issue10227] Improve performance of MemoryView slicing

[Stefan Krah]

Stefan Krah <stefan-usenet at bytereef.org> added the comment:

With Stefan Behnel's slice-object-cache.patch, I get this (PEP-3118 branch):


Linux:   bytes: 0.097 usec  bytearray:  0.127 usec  memoryview: 0.12  usec
Windows: bytes: 0.11 usec   bytearray:  0,184 usec  memoryview: 0.139 usec


On Linux, that's quite a nice speedup.
