Hello all,

I finally managed to run perf with LBR unwinding for user-space call stacks, 
see also:

It really works much better and faster than the DWARF based unwinder. Is 
anyone working on adding support for that to libunwind? It would be really 
nice to have, I think - especially for profilers that use libunwind.
