(1) The CPU Limiter feature allows you to set rules that will limit a process’s CPU consumption by dynamically constraining its CPU affinity (set of CPU cores it can use). For any hard limits on CPU use, this is recommended. Rules are fairly robust. Please see this page for more information. See this page for more info.
(2) The ProBalance algorithm is quite effective at improving responsiveness during high CPU loads. See this page for more info.
(3) Persistent CPU affinity and process priority class rules will enable you a greater degree of control of the allocation of CPU resources.
We recommend giving Process Lasso Server Edition a try! Download from here.
