 Step 1 : Are the Python 3 programs faster? At a glance.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.

Each chart bar shows, for one unidentified benchmark, how much the fastest Python 3 program used compared to the fastest Java 7 -server program.

Look at speed another way - look at a box plot of Time-used data.

 Step 2 : Are the Python 3 programs faster? Approximately.

This table shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.

Each table row shows, for one named benchmark, how much the fastest Python 3 program used compared to the fastest Java 7 -server program.

Python 3 used what fraction? used how many times more?
Benchmark	Time	Memory	Code
pidigits	1/2	1/9	1/7
regex-dna	±	±	1/2
reverse-complement	5×	2×	1/5
binary-trees	13×	±	1/2

Python 3 used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)	1/2	1/2	5×	29×	61×	64×	64×

± read the measurements and then read the program source code.

 Step 3 : Are the Python 3 programs faster? Measurements.

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ≈ CPU Load ~ speed and size.

For each named benchmark, measurements of the fastest Python 3 program are shown for comparison against measurements of the fastest Java 7 -server program.

 Step 4 : Are there other Python 3 programs for these benchmarks?

Remember - those are just the fastest Python 3 and Java 7 -server programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Python 3.

Ada 2005 GNAT ATS C GNU gcc Clojure C# Mono C++ GNU g++ Erlang HiPE F# Mono Fortran Intel Go Haskell GHC Java 7 -server Lisp SBCL OCaml Pascal Free Pascal Perl PHP Python 3 Racket Ruby 1.9 Ruby JRuby Scala

Maybe one of those other Python 3 programs is fastest on a different OS/machine.

 Step 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest Python 3 and Java 7 -server programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
