Course Project Stage 2 part 2: Profiling

After a series of installing different stuff under my own machine, i was finally able to rebuild stage 1 under my laptop.

Stage 1 Rebuild
Since I am continuing under a different machine, I rebuild stage 1.

Home laptop
Aarch64
483,546 kb mkv file
compress 1st test 2nd test
real 8m13.718s 8m13.024s
user 8m11.359s 8m10.813s
sys 0m2.344s 0m2.141s
decompress
real 0m31.880s 0m31.827s
user 0m30.813s 0m30.906s
sys 0m1.031s 0m0.955s

compress 1st test 2nd test
real 23m54.487s 23m47.785s

user 0m21.188s 0m20.828s
sys 0m2.859s 0m3.172s

And from here, begins the profiling

Stage 2 profiling

Gprof
After having to install many many MANY software required on to my own machine AGAIN, I was finally able to run "gprof" but the results was not very satisfying.

I executed sudo gprof /(absolute path)/xz after I used the software to compress a 400M mkv file.
And I assume when all the times are in 0.00, something is wrong.

Perf
I also executed perf record and got an error in which I am stuck on
After spending more than 4 hours with my friends trying to resolve this, I decided to post this and come back to this again tomorrow.

Return from MIA

Ok, it has been more than half a month since my list post. Why I waited so long? Well, it is completely my fault. For the past month my focus was completely on another class in the same semester as this one. I wasn't doing well in that course, so I was trying to shift my balance toward that course and end up with a poor time management result. BUT!! I have shift my attention back to this course and hopefully with the little time left in this course can I catch up with my other classmate without hitting too much penalties. Last post I mentioned that I seeked help from my professor and I was successful in filling some of my knowledge gaps. For the past few days I use my knowledge trying to fully understand some of the code examples provided for students to understand 6502 coding. Currently still in progress. I have scheduled another extra help time slot with professor in a few day, hopefully I can finish my self study of the code example and bring only questions that need

Course Project Stage 2 Introduction

Issue has arrived!! Since I pushed my work for SPO600 till today because of my other focuses in other school works (my own fault), an issue has arrived. Today unexpectedly all the school remote machine rejected all my attempt for connection. A few days ago, there was an email send from the professor talking about all the machines are going through mass restarts on Friday. We were told to expect Aarchie and Israel might continue to be unavailable even after restart because the restart is done remotely. But today I wasn't able to connection to Bbetty and Xerxes as well which are the only other machines I have access to. Now, I have no choice but resort to one of my last resorts. I'll have to enable the windows subsystem for Linux on my laptop and work from there. Since I don't use my laptop for anything other than school work, this will keep my bench marking and profiling errors to minimum. My laptop system type is 64-bit OS, this would cover at least the Aarch64 part of
