 1 : Are the JavaScript V8 programs faster? At a glance.

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

Each chart bar shows, for one unidentified benchmark, how much the fastest JavaScript V8 program used compared to the fastest JavaScript TraceMonkey program.

 2 : Are the JavaScript V8 programs faster? Approximately.

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

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