New issue 2661: pypy3-5.8.0-with-lzma-fixes has slow xz decompression
https://bitbucket.org/pypy/pypy/issues/2661/pypy3-580-with-lzma-fixes-has-slow-xz

strombrg:

pypy3-5.8.0-with-lzma-fixes appears to compress and decompress correctly, but decompression is slower than CPython 3.6's native lzma module's decompression.

Compression is faster on Pypy3 with lzmafii than CPython 3.6 with its native lzma module.

The decompression performance difference is a little over than 30%.
