   Package: linux-perf   
      
   Version: 6.17.13   
      
   In previous versions, I was able to run e.g. `perf record --call-graph   
   dwarf,16384 -m 64M -p ` and it would exit fairly quickly after   
   pressing crtl+C. Now, the same command has been running for over an hour   
   after profiling for about 10 seconds! Every few seconds it prints an error:   
      
   addr2line /path/to/symbols/file.debug: could not read first record   
      
   The way perf invokes addr2line is known to be very slow, but I have   
   previously only encountered that when running `perf script`. `perf   
   record --call-graph dwarf` used to only record stack dumps, not try and   
   symbolicate them, which other tools, e.g. hotspot or samply, are much   
   faster at doing. I believe `perf record` *shouldn't* be trying to do   
   this on its own, at least without being explicitly requested to, and the   
   manpage makes no mention of it.
