I am satisfied because I learned the commands and usage methods that can become the main foundation of performance analysis in a short period of time. In fact, from the perspective of a developer who is not yet familiar with performance analysis, I think that the numerous commands and books with extensive content in Linux can be poisonous. However, I think this lecture is a very compact lecture that creates the beginning of performance analysis based on the “most necessary commands.” I learned good content, and I look forward to the next lectures by the knowledge sharer!
