Is your Linux computer running slow?
Well for me it is very slow. Recently, I upgraded from CentOS 6 to Centos 7. CentOS 6 was lightening fast. Since the upgrade CentOS 7 has been so slow in comparison. But when I say slow, it has been appallingly slow. It just was unable to reach anywhere the performance of 6. Which seems odd, given high transmission speed and powerful hardware. It still takes forever in executing or processing services or applications.

yum command for clearing cache and make
Whilst updating nodejs and npm on a Centos 6 or 7 server running Apache, I hit a few walls and as a matter of process found some commands that are handy to run before doing a deep dive in Google.
Cleaning the cache
