Tango uses state of the art optimizations to minimize the overhead of binary translation. The Technology page describes these optimizations in more detail.
In this page we present a few benchmark results which show the performance of Tango. The benchmark platforms support both 32-bit and 64-bit ARM in hardware to allow for a fair comparison. All benchmarks were compiled as 32-bit ARM code and the resulting binaries were run with Tango enabled ("Translated") and disabled ("Native").
