I am running the command time 7zr a -mx=9 sample.7z sample.log
to gauge how long it takes to compress a file larger than 1GB. The results I get are as follows.
real 10m40.156s
user 17m38.862s
sys 0m5.944s
I have a basic understanding of the difference but don't understand how this plays a role in the time in takes to compress the file. For example should I be looking at real
or user
+ sys
?
