Will URL Rewrite Slow down server

[skuba]

We are thinking about using URL rewrite to make our URLs SE friendly. We still don't know what solution to get: ASAPI Rewrite, ISAPI Rewrite, IISRewrite....
Is there a big difference between those?

Will this slow down our server or increase load?

Thanks

I have never heard of or worked with ASAPI rewrite but if it is a choice between isapi rewrite and iisrewrite i would definitely go isapi. It has lots of nice features and much easier to manage. with IISRewrite you have to make all the rules in 1 ini file and seperate it for different sites on the machine. ISAPIRewrite lets you specify a configuration on a per-site basis. There will be no noticeable slow down or increased load with either component though.

I didn't get which one would slow things down more?
We only need it for 1 site and we have a dedicated server for it.

Thanks

Why not stress test your site before and after adding the module? That's the best way to determine if your site will be slower.

Thanks. The project is done already.
