Proteus-X goes even further than Proteus-S. Proteus-X can load and run a pre-compiled Linux executable without needing the original source code. The whole process environment is emulated and the running code optimised to achieve native speed - sometimes its even faster than native.
- No source code required!
- Full support for multi-threading and dynamic linking
- Built-in X-server for graphical applications
- Can be deployed on any architecture
- The current compiler has demonstrated speeds of 120% native speed on simple programs.
Early performance measurements
Some simple benchmarks are being used to test the speed of Proteus-X. The benchmarks are all compiled with the maximum native optimisation turned on (gcc -O4), with lower optimisation levels Proteus-X typically runs 120% native speed (yes - faster than native).
