Here are some benchmarks, run on a 2.3GHz 8-core i9 macbook pro.

To run these benchmarks, use `make bench PROG=/path/to/program`.
|
||
|
|
|

|
|
`time` is used to measure execution speed. The reported
|
||
|
|
time is the *difference* between the time to run the program
|
||
|
|
with the benchmark input and the time to run it with no input.
|
||
|
|
(This procedure ensures that implementations in dynamic languages are
|
||
|
|
not penalized by startup time.) A median of ten runs is taken. The
|
||
|
|
process is reniced to a high priority so that the system doesn't
|
||
|
|
interrupt runs.
