SharePoint 2010-2013 load test using visual studio, Heavy load on SQL

Hi

Im not sure where to post this question, but here we go.

Using visual studio 2015 enterprise and Visual studio test controller and test agent installed on 3 machines:
vm01 Test controller and Visual studio 2015 enterprise
vm02 Test Agent
Vm03 SQL server for Test Controller.

I am testing a 3 WFE SharePoint farm:
vm04 WFE 1 in NLB
vm05 WFE 2 in NLB
vm06 WFE 3 in NLB
vm07 SharePoint SQL

When running loadtests from the visual studio test machine vm01 towards the SharePoint farm with a defined amount of virtual users; 208 users (Opening different tabs in a site collection). The SharePoint SQL server CPU load quickly goes up to 100%CPU. The SharePoint server CPU loads vary from 30-60%. Memorywise 20% on all SharePoint servers and SharePoint SQL.

Question:
Is it important for the test to keep the SharePoint SQL CPU load beneath 100%, meaning I would have to decrease number of virtual users in my test?
