 Step 1 : Are the PHP 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 PHP 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 PHP 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 PHP program used compared to the fastest Java 7 -server program.

PHP used what fraction? used how many times more?
Benchmark	Time	Memory	Code
pidigits	±	1/12	1/3
regex-dna	3×	1/3	1/2
reverse-complement	3×	2×	1/5
k-nucleotide	10×	1/2	1/2
spectral-norm	26×	±	±
n-body	31×	1/6	±
fasta	33×	1/6	±
mandelbrot	48×	2×	±
binary-trees	92×	2×	1/2
fannkuch-redux	188×	1/6	1/3

PHP used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)	±	±	3×	28×	48×	115×	188×

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

 Step 3 : Are the PHP 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 PHP program are shown for comparison against measurements of the fastest Java 7 -server program.

 Step 4 : Are there other PHP programs for these benchmarks?

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

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

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

Remember - those are just the fastest PHP and Java 7 -server 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.
