Hello > L4Linux.org mentioned: > "Compared to monolithic Linux, there is a small performance tradeoff because of the µ-kernel architecture. However, the initial L4Linux has been somewhat optimized, and on L4/x86 it has a very acceptable slowdown of less than 4 % for any relevant load. > " > Any place can find more detail about the test? > And I'm very curious the L4Linux performance vs "using hardware virtualization on top of L4", have you made any comparison before? It depends. From my experience, I would say, a computation-intenive application demonstrates the same performance as a native application. I/O intensive is another case, here the difference can be from -something (well, uKernels can be faster sometimes) up to +unlimit. Several years ago we measured a network performance from one L4Linux instance to another. At the beggining the performance was near the 400Mb, which was comperable with performance of two VBox-based virtual machines. _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
