Kernel (vmunix) tuning using Spike:
Spike is a tool that performs feedback-based code optimization on
programs. To optimize the kernel a profile was taken using the
Continuous Profiling Infrastructure (DCPI) tool while running a
static HTTP workload. For details see the tuning disclosure.
OS Tuning parameters:
