title: Test Memory Efficiency Comparing Data Structures on a Large Data Set
body: <p>Is there an online resource that I can use that would simulate how a snippet of code would perform on a large data set and provide me with metrics?</p>
  
  <p>Otherwise what method would you suggest to achieve this? (In my case, I specifically want to see how a LinkedList vs ArrayList would perform in terms of memory usage (being able to view bottlenecks over a period of time would be amazing) on inserting a list of things into them read from a 5GB file)</p>
  
  <p>Thanks!</p>
