Kernel One big reason why Linux can boot up faster than Windows is the difference in the way their kernels are designed. The nucleus of an OS is very different in these 2 products. Linux has a monolithic kernel – meaning it holds every core functionality needed by the OS such as drivers ,memory management, task scheduler and the file system. Windows on the other hand contains a micro kernel which contains only the basic necessities and the remaining aspects are loaded separately thus making it a little bit slower when compared to Linux. Backward Compatibility This is one aspect wherein Windows suffers owing to the decades of software support it provides it’s users. While it may slow down the loading process, there’s no denying that a majority of the world’s computing needs require this compatibility. Linux on the other hand, being a minority shareholder in the computing world can afford to forgo backward compatibility. While discussing this, we also need to note that Microsoft can afford for Windows to be slower for the simple reason that a potential user will not be dissuaded from purchasing a Windows license just because it works a little bit slower. Windows being a propriety OS has a limited number of developers and thus a finite number of man hours they can commit. Therefore, the development activities need to be market driven for Microsoft. Optimization is not as high a priority for Windows compared to other requirements. Linux on the other hand outperforms Windows in many areas because it is essential for its existence.

One of the more hidden benefits to linux is that applications share files better than windows. So instead of DLLs like in windows, linux uses .so files, or “shared objects”. There are also .ko files, which are kernel objects, somewhat like drivers in windows. A Windows application might depend on a very specific version of a DLL. The person who writes the application doesn’t know what version of windows you will be installing it on and if that particular DLL will be present in your system. So the easiest solution is to just include the correct DLL with the application. Effect: installers are much larger, C drive is fuller, and more ram is used. Linux does it differently. When you ask to install Midori web browser for instance, apt-get (or the software center front end) checks the package for a list of dependencies. Instead of including all the files, Midori just says what it depends on. So apt-get checks the system and sees that fileX.so.1 is already installed, which is one of the dependencies, so it doesn’t need to fetch it from the central software repository. It then notices that Midori needs another file, which is not installed yet, so it checks the software repository for a version that matches, or one that is newer. It installs that. And so on. Once the dependencies are satisfied, it installs the application itself. Result: Software can be installed very quickly and doesn’t take up as much space or ram. The apt-get system also keeps track of how many applications need fileX.so.1, so that if you remove Midori, it doesn’t remove fileX.so.1, unless nobody else is using it. So Linux has pretty good house keeping skills.
How many of the ardent Linux supporters would stick around if the OS starts having problems ?
