cfbolz changed the topic of #pypy to: PyPy, the flexible snake (IRC logs: https://quodlibet.duckdns.org/irc/pypy/latest.log.html#irc-end ) | use cffi for calling C | if a pep adds a mere 25-30 [C-API] functions or so, it's a drop in the ocean (cough) - Armin

performance seems to improve slightly when I pass --jit off... suspicious, but not sure what that implies
<ronan>
catern: coroutines aren't optimised very well. async stuff adds a lot of overhead which the JIT may or may not remove.

and BTW, cprofile distorts performance a lot on pypy
<catern>
is there a recommended benchmarking tool for programs using pypy?
<catern>
profiling rather

catern: we still recommend vmprof, but the server upload is not working, you have to use the self-host option to visualize the results
<mattip>
.. and for c code, I hope you are using cffi rather than cython/C-API wrapping
