title: Datasets for cache hit-rate evaluation
body: <p>I'm implementing a new eviction strategy for caches. In order to compare its hit ratio to a regular LRU cache, I would like to use data traces from actual systems (like server requests or virtual memory accesses), that I can replay with my cache and measure needed metrics.
  Surprisingly, I found very few such traces, the biggest one is Wikipedia access traces. </p>
  
  <p>What are other sources for such traces? 
  What are common benchmarks for evaluating cache efficiency?</p>
