AFAICT, AMD A6-4400M supports hardware virtualization (aka KVM in the
Linux world).  I'd recommend you to try using qemu-kvm instead of
qemy-system-x86.  That should improve the performance noticeably.

In addition, the SL image you've downloaded is 64 bits.  I don't know if
you try to run that via qemu-system-i386 or qemu-system-x86_64.  The
former is 32bit /emulation/, the latter 64bit.

But only qemu-kvm uses virtualization.

Try also to kick off your images using virt-manager.  It's usually
fairly simple to configure new VMs that way, and just point it to your
images.  This way, virt-manager/libvirtd will take care of setting up
the proper arguments to qemu-kvm, for better performance.  Also try to
use the virtio drivers wherever possible, as they don't require the
complete hardware emulation layer.
