I haven't filed a bug yet because I'm not sure what component to assign this too. I upgraded to Rawhide this morning and noticed that some tests that previously ran OK are now timing out. It turned out that the tests were failing because a valgrinded executable runs much more slowly in Rawhide today.
Here's my test: Upgrade to Rawhide and install these additional packages: # dnf install libnbd nbdkit valgrind Unpack the certificates from http://oirase.annexia.org/tmp/rawhide-valgrind-bug/pki.tar.gz into /tmp Run this command as NON-root (it's self-contained and just connects the two commands together over localhost port 10809): $ time nbdkit --tls=require --tls-certificates=/tmp/pki null --run 'valgrind nbdinfo nbds://localhost' For me this takes over 40 seconds in Rawhide, versus a couple of seconds in Fedora 33/34. Also if you remove "valgrind" it runs instantaneously even in Rawhide. If you run it as root, it runs quickly again (WTF!) The perf flamegraph seems to indicate it's doing a lot of stuff with DWARF 3 symbols. http://oirase.annexia.org/tmp/rawhide-valgrind-bug/libnbd.svg Uninstalling all relevant debuginfo packages didn't seem to help.
