I am experimenting now with various compression in Fedora and noticed slowdowns with

HDD.
Also, please include the exact kernel version in the bug report.
Either the literal file name or the rpm - because we need to know if
it's a debug enabled kernel. Fedora debug kernels enable
CONFIG_LOCKDEP which slows down Btrfs dramatically more than other
file systems.
