Total used free shared buffers cached

Under Linux the free memory shown in first line is actually
wasted/unused/un-utilized memory.
In the second line you can actually see the free memory which is a sum of
cached+buffers+free.
Now as to why the server is slow can be dependent on many reasons.
What hardware and software configuration do you use.
Have you shutdown all the unused services etc.
A few kernel and HDD optimizations ( sysctl , hdparm ) may be in order.
Or better still a kernel recompile.
