In this section we showed the lowest achievable noise footprint
in the Linux kernel with runtime and compile time
configurations. However, this footprint is very similar to
the noise that was identified to be a scalability bottleneck
to BSP applications at high scales [17]. We argue that the
time spent in tick processing is not needed by the application
and it only causes delays and can be removed or moved to
spare cores. A complete removal of the ticks might be necessary
to achieve a consistent noiseless and scalable system.
We address this in the next section.
