I'm trying to measure the CPU% consumed by my app on a multi-core machine, meaning htop CPU% reports can go over 100%. I'm trying to get a simple read on CPU usage difference when I run my app in one configuration vs. another, but the change is likely less than 1% CPU and I'm seeing the following "107." for my process:
I guess they hardcoded the CPU% column to only support 4 characters... is there a way to expand the width of this column so I can see fractional parts of three digit CPU% values? Ideally two digits of precision past the decimal.
