Both from startup performance and hot performance are interesting, depending on use-case (for a long-running server, hot performance is interesting; for a short-run script, including warmup is significant). I'd suggest providing both figures for PyPy. /gsnedders _______________________________________________ Speed mailing list Speed@python.org https://mail.python.org/mailman/listinfo/speed
