 ### Background
 
-For network applications such as firewalls and load balancers to use DPUs there needs to be significant performanance benefits. Therefore this set of requriements focuses on the areas that require a significant amount of x86 CPU for these type of applications. Ideally the performance improvemenst should be in the range of at least one order of magnitude as there is both a CAPEX and OPEX costs for the end customers.
