Hi,
you got almost all your physical memory used, you should think about add
memory.
Anyway, swapping is managed by the kernel. You can set an higher
swappiness parameter value, 100 for example, in the file
/proc/sys/vm/swappiness. This allows you to set how much the system will
swap.
echo 100 > /proc/sys/vm/swappiness
To make your set available at reboot you have to set it in the file
/etc/sysctl.conf. Add the following line:
vm.swappiness=100
