Seeing as she is his clone with the same physical stats and doesn't have to carry around an adamantium skeleton... she should realistically be faster. If we are to go by feats, she beat the training simulation Wolverine partook in quicker than he did when she was around 11.
She hasn't been around as long as he has and doesn't get the spotlight treatment, so of course her feats aren't quite as obscene on the high end as his are.
In any case, she has shown to have a healing factor at precisely his level, the speed to and fighting skill to bleed Logan out, the guts to take nearly fatal blows on purpose to pwn Deathstrike, etc.
