Hi Arnaldo,

YES, I need further help.

I have published in [1] numbers for "perf stat make ..." with
GNU/gcc+binutils vs. LLVM toolchain for building Linux v5.8-rc7.

[ GNU/gcc+binutils toolchain ]

   10964.876434769 seconds time elapsed

   29666.464675000 seconds user
    2149.943729000 seconds sys

[ LLVM toolchain ]

   17149.393417675 seconds time elapsed

   47787.158036000 seconds user
    2289.196142000 seconds sys

How can I dig further to see why the time for user is higher when
building with LLVM toolchain?
Any suggestions?

Thanks.
