The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why Is Jepsen Written in Clojure?
Speaking very loosely, primitives on the JVM are values which are represented directly in memory, instead of as pointers to objects on the heap. Clojure generally treats everything as a pointer to a heap object. There is no specialized equivalent for, say, a vector of shorts, or a map where values are floats. The compiler can emit specialized function signatures for... IIRC longs and doubles, but other types (e.g. byte, float) aren't directly accessible--they go through widening conversion. It's also easy for the compiler to quietly fail to recognize it can preserve primitives in some kinds of loops, so you wind up with what Java calls "autoboxing": wrapping a primitive in a corresponding Object type.
Here's a recent example of some code in a hot path inside Elle, one of Jepsen's safety checkers. It does a lot in primitive, packed structs and bitmasks to avoid pointer chasing.

There was actually a Clojure version of this earlier that got pretty close perf-wise, but I wound up dropping to Java for it instead:
