I did a search on "CPU family 15 Model 79 Stepping 2" and this is what I
found.
http://www.cpu-world.com/CPUs/K8/AMD-Sempron%2064%203400%2B%20-%20SDA3400IAA3CN%20%28SDA3400CNBOX%29.html
And here is the benchmark I found
http://www.cpubenchmark.net/cpu.php?cpu=AMD+Sempron+3400%2B
I would say at least in part the cause of your computer being slow is
the CPU.
I'd be interested to hear if more RAM makes a difference. Of course RAM
might effect performance if you are doing something that requires a lot
of RAM. I assume more RAM will effect compile speed.
This is a testament to Linux breathing life into old iron.
