Cool Hidden features in OKL4 2.1 (Part 2)
2. OK Linux performance on IA-32
With OKL4 2.1, we've released a series of additional performance optimizations to OKL4 and OK Linux on ia32 architectures. And by additional improvements I really mean freakin' huge optimizations. This baby flies compared to the achieved performance of OKL4 1.5.
To give you a taste, let me highlight a few carrots. LMbench's fork and exec benchmarks show OK Linux outperforming KVM on a Core 2 Duo (E6400) by a factor of 4 to 5. And taking the well known 'linux kernel compile' benchmark, which is a pretty good way of measuring something close to the 'realistic worst case' performance of a virtualization solution, we see OK Linux exhibiting only 8% overhead over native Linux, whereas KVM suffers as much as 28%. Nice, eh ?
