The easiest way is to re-install with an /amd64 ISO.

When addressing more than 4 GB of physical RAM, a native
64bit system is certainly more efficient (hence quicker)
than the PAE kludge.

Yes it will. With /amd64, the address space is larger
than 4 GB. With /i386, it is always limited to 4 GB,
no matter if you use PAE or not. (Actually the address
space for user processes is even more limited: 4 GB
minus the kernel's address space.)
