OSNews, Generic OSes It's recently been a year since I started working on my pet OS project, and I often end up looking backwards at what I have done, wondering what made things difficult in the beginning. One of my conclusions is that while there's a lot of documentation on OS development from a technical point of view, more should be written about the project management aspect of it. Namely, how to go from a blurry "I want to code an OS" vision to either a precise vision of what you want to achieve, or the decision to stop following this path before you hit a wall. This article series aims at putting those interested in hobby OS development on the right track, while keeping this aspect of things in mind.

in all of them icc beats GCC by quite a large margin, not to mention icc is much faster at doing the actual compiling, too. Quite surprising.


Well *I* am not surprised: remember that very recently distribution have changed their JPEG rendering libraries with a 20% performance improvement.
You can see this in two ways:
- the optimistic view: nice a 20% improvement!
- the realistic view: JPEG are very old, the improved library use ISA which are very old too, why only now do we have the 20% improvement?

My view is that: open-source developpers like to have very flexible software combinations so GCC compiles many language on many architecture, but from a performance POV the situation isn't very good..
