Hello!
We still don't have performance numbers for D-bus using AF_UNIX
multicast since our D-bus daemon branch is still not stable. But Alban
did some tests for the first approach (creating a new socket address
family AF_DBUS) and the performance gain was x1.8 for KVM/i386 and x3
for N900/ARM.
I did not ask for the performance improvement in artificial benchmarks,
they will obviously show some :)
What I am interested in is a test showing that _in_real_world_, the system
spends considerable amount of time by passing messages. That is, a reason
for optimizing the thing at all.
Have a nice fortnight
