Accessible software performance

Nowadays, in the software industry, we already have a lot of ways to improve performance of our applications: compilers become better and better each year in the optimization field, we have a lot of tools like Linux perf and Intel VTune to analyze performance. Even algorithms are still improving in various domains! But how many of these improvements are actually adopted in the industry, and how difficult it is to adopt them in reality? That's an interesting question!

In this talk, I want to show you:

• Why accessibility of software performance matters
• How various software optimization approaches are different from the adoption easiness perspective: from different compiler optimizations to semi-automatic optimizations to a manual approach
• What things can be improved and how
• Many related open-source examples from my practice
• Share with you an idea behind the "Software performance" devroom

I hope after the talk you get an interesting perspective on software performance to think about.
