The network performance was measured using the run script
"netperf_lwip", the Genode core compilation is measured using
"noux_tool_chain_auto". Both run scripts can be found in the 'ports'
repository, under 'repos/ports/run'.

Thank you. We will use them for our tests.

It's just an assumption, as I said I don't know whether the developers
of Fiasco.OC fixed the SMP performance weakness in a more recent
version. The following e-mail from Christian Prochaska on the l4-hackers
mailing list explains the SMP problem in more detail:

http://permalink.gmane.org/gmane.comp.micro-kernel.l4.devel/4896

I'll run L4Linux on L4Re on both the kernels(old and new). If I can find significant performance improvement then I'll try to run over Genode.

Just a warning: if you're planning to upgrade to a more recent version
of Fiasco.OC, don't expect that everthing will run out-of-the-box.

If there are some issues like makefiles and toolchains, I might be able to handle them. Otherwise, I'll get back to you.

Thanks and Regards

Praveen
