Here further evidence to prove a point: Obito was under the influence of the power of the Tailed Beast, boosting its power. Kakashi was under that same influence, boosting his power too, not to mention that Naruto has given Kakashi chakra throughout the war.

http://narutobase.net/manga/Naruto/666/14/ Madara sends 2 Truth Seeking Balls towards Kakashi and Obito.

http://narutobase.net/manga/Naruto/666/15/ The orbs approach them and they still haven't moved. At the bottom panel, you see them activating Kamui at once. Before you argue that both eyes aren't in the same body - that doesn't matter, say they both has extreme skill in utilizing the technique itself, while it being enhanced by various chakra. Kamui, when being used at once, doubles its activation time, thus its speed.

http://narutobase.net/manga/Naruto/666/16/ In the first panel, it shows Obito being teleported, while both Truth Seeking Balls are in front of them.

If Kamui was instant, they those orbs wouldn't have gotten any closer to them, proving my point. Sayuri doesn't possess Tailed Beast Chakra, which enhances it to the point that Obito and Kakashi was using it at.

When obito had both MS, she had the Tailed Beast removed from him by MAdara, lowering its power, thus proving my point again.

I'm not arguing about your character, but the speed of the technique is greatly misunderstood.
