Here are few excepts of feedback we received:</p> <div class="section" id="lwn-short-experiment"> <h1>LWN short experiment</h1> <p>LWN has a tool they use for parsing “git log”'s output in order to do analysis on the contributors to the Linux kernel. Simply <a class="reference external" href="http://lwn.net/Articles/442268/">by switching to PyPy</a> they were able to get a 3x speedup, from 63 seconds to 21 seconds, compared to CPython.</p> <p>“In other ways, PyPy is ready for prime time; it implements the (Python 2.x) language faithfully, and it is fast.”</p> </div> <div class="section" id="myhdl"> <h1>MyHDL</h1> <p>MyHDL got a speed up by <a class="reference external" href="http://www.myhdl.org/doku.php/performance">6-12x compared to CPython</a>, on a range of benchmarks, putting it in the same league as other HDL implementations.</p> <p>“By simply changing the Python interpreter, MyHDL is playing in the same league as Verilog and VHDL simulators. This is a remarkable achievement, given that Python's power stays completely available. There is no reason anymore to avoid MyHDL because of performance concerns.”</p> </div> </div> <div id="sidebar"> </div> </div> </div> </div></div></div> </body> </html>
