I discovered this while playing with #4612.
This is with the old gmp, i.e. not the new eMPIRe, but that also shows
roughly the same numbers:
{{{
sage: get_memory_usage()
790.43359375
sage: time len([a for a in srange(10**5) if not
(-a^3).is_perfect_power()])
CPU times: user 0.27 s, sys: 0.03 s, total: 0.30 s
Wall time: 0.31 s
24128
sage: get_memory_usage()
798.4765625
sage: time len([a for a in srange(10**6) if not
(-a^3).is_perfect_power()])
CPU times: user 2.84 s, sys: 0.27 s, total: 3.12 s
Wall time: 3.12 s
241224
sage: get_memory_usage()
868.921875
}}}
Valgrinding this didn't turn up anything useful. Thoughts?
Cheers,
Michael
