Comment (by vdelecroix):
Looks like it is
{{{
sage: S1=set(range(10))
sage: S2=set(range(10,20))
sage: timeit("if S1&S2: pass",number=1000000)
1000000 loops, best of 3: 446 ns per loop
sage: timeit("if len(S1&S2): pass",number=1000000)
1000000 loops, best of 3: 517 ns per loop
}}}
50ns... it will save a lot of time!
