comment Need to search for files in a linux directory that has 256 sub-directories, but want to bypass empty directories
Without more info, it seems that derobert's find command fits the bill perfectly.

comment What is the relationship between root and kernel?
@RonVince It depends on what parts of the system you would like to learn. For some of the questions you have been asking, I would recommend a combination of /Advanced Programming in the Linux Environment/ by W. Richard Stevens and your system's development manpages.

comment Read the middle of a large file
You've likely identified the right cause. Note however, that you'll also need to adjust the skip I believe as that is also in BLOCKs. In new versions of GNU dd there are count_bytes and skip_byes iflags that allow you to specify the count and skip in bytes.

@user3086014 I'm sorry, but I won't be putting more work into this answer. Take a look at the Ruby example I have there. It should give you a good place to start on how to get tags out of various parts of the JSON you want.

comment libpam load pam modules at every connection
Out of curiosity, did your debugging actually show that PAM loading was slow compared to the other parts of starting the session? If so, is PAM doing a lot of work to do authentication or is it really just the loading that is slow? Sorry to ask so many skeptical questions, it is just very surprising to me. I would expect other portions of the connection to dwarf simply loading the PAM modules. For example, if you have "UseDNS" set to yes.
