Have a question for anyone with experience in the area of Boost and Performance Licenses.
In researching the Boost License, it seems this is the way to go to unlock (un-cap) the routers full throughout potential. Are there any circumstances when one would prefer the Performance License over the Boost License? The boost license seems obvious and the sure way to go.
the performance license is a whole lot cheaper (around $1,200) than the boost license (around $2,500). It all depends on what bandwidth you need...
what are you looking for, that is, what does your topology look like ? Below is a link to general software configuration guides...
Old thread but hope below helps to anyone who comes to see this page in future.
ISR 4000 Performance on Demand license
Common for the new 4000 Family is that all platforms come with fixed maximum performance levels. One fixed base performance level is delivered as factory default with an optional performance-on-demand license to increase the base forwarding throughput. This scenario enables deployment in high-speed WAN environments through performance-on-demand licensing to double or, for one of the platforms, triple the router capacity without any hardware upgrades.
All 4000 platforms have their fixed performance levels set well within actual capacity, with the result that performance does not necessarily degrade when a service is added to the configuration. This setup provides a deterministic performance, eliminating a network administrator’s guesswork when planning for new services.
For a more detailed document on ISR 4000 Series Performance and Platform Scalability, please refer to the Performance Whitepaper at https://www.cisco.com/c/en/us/products/collateral/routers/4000-series-integrated-services-routers-isr/white-paper-c11-734550.html
ISR 4000 Boost License
In addition to the Performance License, customers may now order a Booster (or Boost) License that allows the router to perform between five or more times than that of the throughput with Performance License. In contrast to the deterministic performance described above, in the Booster mode, the router does not provide the deterministic level of performance as provided when operating with the default license or with the Performance license.
The Boost License provides a license tier above the Performance License allowing customers to completely remove the ISR4000’s performance limiters. This will make the ISR 4000 platforms perform at entirely new performance levels, allowing for 4+ Gbps of IP Routing (CEF) performance on the 4400 series ISRs. For deployments using encryption, IPSec throughput with AES 256 increases to 250Mbps on the lowest platform up to 10Gbps on the ISR4461.
