Each chart bar shows , one ↓  .

These are not the only programs that could be written. These are not the only compilers and interpreters. These are not the only programming languages.

Column × shows how many times more each program used compared to the benchmark program that used least.

  benchmark : 

diff program output N = 10 with this 1KB output file to check your program is correct before contributing.

We are trying to show the performance of various programming language implementations - so we ask that contributed programs not only give the correct result, but also use the same algorithm to calculate that result.

Each program should

Note: this is an adaptation of a benchmark for testing GC so we are interested in the whole tree being allocated before any nodes are GC'd - which probably excludes lazy evaluation.

Note: the left subtrees are heads of the right subtrees, keeping a depth counter in the accessors to avoid duplication is cheating!

Note: the tree should have tree-nodes all the way down, replacing the bottom nodes by some other value is not acceptable; and the bottom nodes should be at depth 0.

Note: these programs are being measured with the default initial heap size - the measurements may be very different with a larger initial heap size or GC tuning.

Please don't implement your own custom memory pool or free list.

The binary-trees benchmark is a simplistic adaptation of Hans Boehm's GCBench, which in turn was adapted from a benchmark by John Ellis and Pete Kovac.
