Do route filters have a performance hit?

[manicomio]

Does having too many route filters affect the performance of the server? Switching from a vB4 install, I plan on making some route filters for my most active members in the style of domain.com/username for around my top 50 members, I don't know if having too many filters taxes the server much more than normal load? If it does, how many route filters is too many, 50, 100, 500, 1000, more?

Or is there a simple hack to make all member user pages in the style of domain.com/username?

It wouldn't really be a noticeable difference.
