Cisco show mem vs show processes memory sorted

For me to check the router or firewall cpu usage and the memory usage, i always issue the show mem or show processes cpu to see what is causing the router to have a high CPU or memomry utilization. However, i realised that the show mem command output is not as nice as it seemed to be. I was looking at ioshints blog and found out the same command with a little tweaks here and there. This command provides a better output than show mem which is very important for troubleshooting purposes. See below:

show processes memory sorted

show processes cpu sorted 1min

show processes cpu sorted 7min
