within the kernel is dangerous. For example, a common bug such as a buffer overflow within TUX could give an attacker superuser control over the machine. Therefore, it is much safer to keep the HTTP daemon entirely within userspace, where a bug does not necessarily give an attacker total control. Project status Tux has been found to be largely unnecessary as modern kernels and web servers can supply similar speed advantages as Tux did, without the in-kernel downsides. There are other options for high-performance static web servers in Linux. Nginx found its path to popularity in party by extremely fast serving of static content.
