Puppy's speed is evident in Quirky, but other factors are different. For instance, Quirky does not use SFS (Squash File System) modules to add software packages. It does not require a session save-file to create persistent memory. It does not need the initrd.gz to boot. Quirky also does not use GTK 2.24.x for rendering as does Puppy Linux.
