| + | The PHP CLI benchmark is a script that runs several algorithms and test runs and gives back results in forms of memory consumption or cache misses depending on which tool that is used. The algorithms that are used are similar (or clones) to the ones used in the V8 javascript benchmark and the Sunspider javascript benchmark. | ||

| To compare the results it's possible to use the --comparison option. In example, if you would like to compare results from 5.X with memory usage the command could be following: | To compare the results it's possible to use the --comparison option.
