Impact of address list timeouts on resources

Hello,

Does anyone here know if the address list timeouts have any substantial impact on resource use?

I have a couple use cases where I’d like to be able to glance at my address lists and have a rough idea for how long an address has been in the list. One use case is to able to script a basic trending traffic analysis based on the lists. Tracking addresses for up to 30 days is my goal right now. I can use address list timers to help with this, but if the address list timers substantially impact system resources, this could have unintended consequences. For example, a DDoS attack’s effect would be amplified by filling my address lists with thousands of addresses that each have a 30 day timer running. If the timers use a substantial amount of resources, the system might fold sooner than it would otherwise.

Thanks
