Hey everyone,
I am looking at the FL-4320-BOOST-K9 license for an ISR 4320 that has started to struggle during heavier traffic hours. The router still works fine, but once we stack a few IPSec tunnels, NAT, and some basic routing tasks on top, it feels like it hits a ceiling faster than it used to. The BOOST license is supposed to open up more performance headroom, but I have heard mixed things depending on the IOS XE version and the type of traffic running through the box.
If anyone has enabled ORM Systems FL-4320-BOOST-K9 recently, did you actually notice a real improvement under load, or was it mostly theoretical? Any issues during activation? Appreciate any insight.
