Recently I have been investigating one of my Linux server's speed using the copy [cp] command.  This came about due to 'upgrading' the server from Centos 6 to 7.  Once I had migrated a domain, I ran the following command yes | cp -rf 'stg/core' 'tmpdir'To my surprise, the first run of this command took over 38 minutes to complete.  Crap!  Yes a simple cp -a command is a very painful and slow process.  Read more about the pain and times under Centos 7 in this...
