title: Google Compute Engine machine type comparison - slower performance with higher number of CPU and RAM storage
body: <p>I am running code (particularly related to Gaussian Processes) on Google Compute Engine VMs and I am trying to reduce the overall computation time by increasing the vm's number of cores and memory. However what I notice is that when switching for example from 'n1-standard-1' to 'n1-standard-4' (<a href="https://en.wikipedia.org/wiki/Google_Compute_Engine#Regions_and_zones" rel="nofollow noreferrer">look at machine types</a>) I get an overall slower performance. </p>
  
  <p>Intuitively I do not understand why this is happening or if I am missing something. </p>
  
  <p>Please let me know if I should provide with any further details. </p>
