Does anyone have a link that explains how ACLs are processed?

[RookThis]

Does anyone have any information explaing how ACLs are processed. I have a reflexive access list that I've applied to a particular subnet and the users are complaining that it's slower than when they work off machines that are not restricted. With that in mind I am thinking it's possibly the ACL that is slowing them down. I want to understand how the ACLs are handled when flows are received by the router, and to see if I can tune something to make things faster.

Thanks,
