Just built an image for the raspberry pi without the witness options.. Will try to build with TARGET_ARCH=3Darmv6hf later on. Eager to test the performance of tornadoweb on the rpi first. :) Will come back with benchmarks later. What else would be nice to benchmark? Is there a standard set of benchmarks that I can run and provide results for? 2015-05-13 17:04 GMT+02:00 Warner Losh <imp@bsdimp.com>: > > > On May 13, 2015, at 5:27 AM, Andreas Andersson <aandersson@tappsi.co> > wrote: > > > > I do understand this is still very new and not ready for "producton" us= e. > > > > But freebsd 11 on rpi2 suffers permance issues.
