Hi Achim,

  Is the Cygwin version of objdump build with debuginfod support enabled ?

  If so, does adding -wE or --dwarf=do-not-use-debuginfod to the command line
  improve the performance times ?

  I suspect that the presence of the -l option is the trigger for the slow
  down, since this means that the debug information has to be processed in
  order to determine the line numbers.  Processing DWARF is a slow business
  and it has only become slower over successive releases as bug fixing means
  that more care has to be taken to handle all the possible intricacies.

  Hence - as a workaround, could you omit the use of the -l option ?

Cheers
  Nick
