There was a PSF-sponsored effort to improve the situation with the<br>
<a href="https://bitbucket.org/pypy/codespeed2/src" target="_blank">https://bitbucket.org/pypy/codespeed2/src</a> being written (thank you<br>
PSF). It's not better enough than codespeed that I would like, but<br>
gives some opportunities.<br>
<br>
That said, we have a benchmark machine for benchmarking cpython and I<br>
never deployed nightly benchmarks of cpython for a variety of reasons.<br>

for py3k because benchmarks are mostly missing<br></blockquote><div><br></div><div>Missing how? <a href="http://hg.python.org/benchmarks">hg.python.org/benchmarks</a> has plenty of Python 3-compatible benchmarks to have interesting results.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I'm willing to set up a nightly <a href="http://speed.python.org" target="_blank">speed.python.org</a> using nightly build<br>
on python 2 and possible python 3 if there is an interest. I need<br>
support from someone maintaining python buildbot to setup builds and a<br>
VM to set up stuff, otherwise I'm good to go<br></blockquote><div><br></div><div>I suspect there is interest.</div><div><br></div><div>-Brett</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

DISCLAIMER: I did facilitate in codespeed rewrite that was not as<br>
successful as I would have hoped. I did not receive any money from the<br>
PSF on that though.<br>
