Comment (by tscrim):
With #11187, on my laptop (see comment:4) I get
{{{
sage: W = ReflectionGroup(['E',8])
sage: %time for x in W.iteration('depth', False): pas
CPU times: user 8min 44s, sys: 38.2 ms, total: 8min 44s
Wall time: 8min 43s
}}}
There are a number of changes from #11187 (the cythonization) that could
be lifted up to be used for the general Coxeter group iteration.
