Impact of large address group

What is the performance impact of having many addresses to match against?  If I have an address group that has hundreds of individual addresses in it (some FQDN), others ip netmask, will it have a noticible impact on performance?  We are using a 2050 primarily for URL filtering.

We do not have any published numbers for such a test case.  If possible try to use a subnet  to aggregate groups of devices and minimize the number of "look ups" that have to be made. But I think the impact will not be noticable.

In this case, the addresses cannot be represented by subnets or vlans as they are individual nodes across all our subnets and vlans.  I noticed in the config that there is a stated limit of 10,000 under config/devices/platform/limits but I also noticed that in the same area there is a limit of 500 addresses in an address-group.  I will take this as the practical limit for us.
