> Benchmark parameters:
> * 100% put of 25 million unique entries, 1 thread
> * then 100% get of 25 million entries, 1 thread

> !kv-put.png!
> "get" throughput:
> !kv-get.png!
> On the graphs we see the performance drop which happen every 5 minutes which
> begins after ~50 minutes since the start of the test. Then after ~4 hours and
> 20 minutes the periodic drops stopped to appear.
