NICTA's virtualised Linux faster than native on L4-embedded

[Gernot Heiser]

NICTA's ERTOS team is proud to release LMBench performance figures for
Wombat, our architecture-independent para-virtualized Linux running on
L4-embedded/Iguana. The benchmarks show that Wombat's
context-switching overheads are up to thirty times lower than those of
native Linux on an XScale processor.

This result, which is due to Wombat benefiting from the
fast-context-switching support provided by NICTA's L4-embedded,
demonstrates that L4-embedded/Iguana is the leading high-performance
microkernel and embedded virtualisation technology, particularly on
ARM processors.
