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

Each chart bar shows, for one unidentified benchmark, how much the fastest Scala program used compared to the fastest JavaScript V8 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 Scala programs faster? Approximately.

Each table row shows, for one named benchmark, how much the fastest Scala program used compared to the fastest JavaScript V8 program.

Scala used what fraction? used how many times more?
Benchmark	Time	Memory	Code
k-nucleotide	1/10	1/2	5×
reverse-complement	1/6	±	2×
fasta	1/3	3×	±
binary-trees	1/2	±	±
n-body	1/2	3×	±
spectral-norm	±	2×	±
fannkuch-redux	±	4×	2×
regex-dna	9×	2×	2×

Scala used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)	1/10	1/10	1/4	1/2	±	2×	9×

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

 3 : Are the Scala 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 Scala program are shown for comparison against measurements of the fastest JavaScript V8 program.

 4 : Are there other Scala programs for these benchmarks?

Remember - those are just the fastest Scala and JavaScript V8 programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Scala.

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

 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest Scala and JavaScript V8 programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
