Nowadays real machines have lots of RAM and SSDs: https://forums.opensuse.org/showthread.php/541321-Upgrading-the-Hardware Any recent SSD with 6.0 Gb/s will boost performance. Your 4 GB RAM and HDD are a really bad bottleneck. Running btrfs on top of inadequate hardware makes things worse. Most significant changes I made int the past decade to my machines and builds for other users are adding memory and replacing HDDs by SSDs.
By the way there is a bug in btrfsmaintenance which affects some users: https://en.opensuse.org/SDB:Fix_btrfsmaintenance-refresh
You my show the output of inxi -zmFxxx when running Leap.
