My first thought is to ask what the machine is being used for.  It is
not normal to have apache/php/mariadb and firefox/browsing on the same
machine.  Usually you have either a server (and therefore no desktop
processes), or a desktop (and therefore no server processes of
particular relevance).  So what are you doing with the system?  What is
it that is using the I/O ?  Is the machine really too slow, and what do
you /feel/ is slow on it?

My second thought is that often the best way to improve I/O performance
is to add more ram.  Is that a possibility with your hardware?
