Clojure vs Haskell GHC | Computer Language Benchmarks Game

1 : Are the Clojure programs faster? At a glance.

Each chart bar shows, for one unidentified benchmark, how much the fastest Clojure program used compared to the fastest Haskell GHC program.

These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.

2 : Are the Clojure programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Clojure program used compared to the fastest Haskell GHC program.

Clojure used what fraction? used how many times more?

3 : Are the Clojure programs faster? Measurements.

These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.

For each named benchmark, measurements of the fastest Clojure program are shown for comparison against measurements of the fastest Haskell GHC program.
