                      Experimental results
 ============================================================
 
+Our tool-chain is capable of translating the Python interpreter of PyPy,
+written in RPython, producing right now ANSI C code as described before,
+and also LLVM [#]_ assembler then natively compiled with LLVM tools  
+
+.. [#] the LLVM project is the realisation of a portable assembler
+       infrastructure, offering both a virtual machine with JIT
+       capabilities and static compilation. Currently we are using
+       the latter with its good high-level optimisations for PyPy.
+
+The tool-chain has been tested and can sucessfully apply
+transformations enabling various combinations of features. The
+translated interpreters are benchmarked using pystone (a Dhrystone_
+derivative traditionally used by the Python community, although is a
+rather poor benchmark) and the classical Richards_ benchmark and
+compared against CPython_ 2.4.3 results:
