 Step 1 : Are the Go 6g 8g 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 Go 6g 8g program used compared to the fastest C++ GNU g++ program.

 Step 2 : Are the Go 6g 8g 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 Go 6g 8g program used compared to the fastest C++ GNU g++ program.

Go 6g 8g used what fraction? used how many times more?
Benchmark	Time	Memory	Code
chameneos-redux	±	1/2	1/2
n-body	±	±	±
binary-trees	±	±	±
spectral-norm	2×	±	1/3
fannkuch	2×	1/2	1/2
reverse-complement	2×	1/2	1/4
mandelbrot	3×	±	±
fasta	3×	±	±
regex-dna	30×	7×	1/3
k-nucleotide	41×	8×	1/4

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

 Step 3 : Are the Go 6g 8g 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 Go 6g 8g program are shown for comparison against measurements of the fastest C++ GNU g++ program.

 Step 4 : Are there other Go 6g 8g programs for these benchmarks?

Remember - those are just the fastest Go 6g 8g and C++ GNU g++ programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Go 6g 8g.

Maybe one of those other Go 6g 8g programs is fastest on a different OS/machine.

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

Remember - those are just the fastest Go 6g 8g and C++ GNU g++ programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.

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