Hello pypy experts!
What I want to do is to run a performance test on the cpyext module. The
translation&compilation procedure took about 1 hour on my computer. After I
modifying some code( just a slight modification under pypy/modules/cpyext), the
whole translation procedure seemed to restart completely, taking another one hour.
I found pytest could do unit test, but it seems to be run on a different
interpreter such as Cpython2 or another pre-built pypy interpreter.
So I was wondering if there is any way to run performance benchmarks partially,
without compiling the whole project, honestly thanks!

The short answer is "you need to do a complete translation in order to
benchmark". But you can run some microbenchmarks like in this blog post
[0] and use kcachegrind to look for inefficiencies if you know what you
are looking for.
Is there some particular code pattern you would like to speed up?
