Comment (by tscrim):
With patch:
{{{
sage: %time C = CrystalOfLetters(['D',100])
CPU times: user 1.54 s, sys: 0.03 s, total: 1.56 s
Wall time: 1.72 s
sage: B = InfinityCrystalOfTableaux(['B',3])
sage: S = B.subcrystal(max_depth=4)
sage: %time G = B.digraph(subset=S)
CPU times: user 28.20 s, sys: 0.03 s, total: 28.23 s
Wall time: 28.62 s
sage: %time G = C.digraph()
CPU times: user 0.33 s, sys: 0.00 s, total: 0.34 s
Wall time: 0.34 s
}}}
Before:
{{{
sage: %time C = CrystalOfLetters(['D',100])
CPU times: user 1.84 s, sys: 0.02 s, total: 1.86 s
Wall time: 2.00 s
sage: sage: %time G = B.digraph(subset=S)
CPU times: user 28.96 s, sys: 0.03 s, total: 28.99 s
Wall time: 29.94 s
sage: C = CrystalOfTableaux(['D',4], shape=[2,1])
sage: %time G = C.digraph()
CPU times: user 0.39 s, sys: 0.01 s, total: 0.40 s
Wall time: 0.39 s
}}}
So currently I'm seeing small performance gains, the bigger ones are
likely going to come from #14686.
