Hi all,
I’ve two identical Linux systems with only kernel differences.
What are the differences in the kernels?
You didn't answer this question, is this the same kernel source being compared here? Same version? Same compiler? Everything identical?
Both systems are having exactly the same hardware configuration. Compiler and kernel versions are different. One system has Ubuntu 16.04.4 LTS(4.4.0-66-generic kernel with gcc version 5.4.0) kernel and the other one has Ubuntu 18.04.4 LTS(4.15.0-91-generic kernel with gcc version 7.5.0).
Those are _very_ different kernel versions, with many years and tens of thousands of different changes between them. Hopefully the newer kernel is faster, so just stick with that :) greg k-h
