 Table~\ref{tab:functions} lists all functions presented in the course and their implementation status in \texttt{intercept.so}.
 As one may see, simple file stream functions are not currently implemented in \texttt{intercept.so}.
 This is because of time restrictions on this work and the fact, that simple file operations may be tested easily in the conventional way of checking the resulting output.
+Note, that the future implementation of single functions is not very complex.
 All other functions have at least interception and mocking (returning, failing) implemented.
 For some functions the modification of function arguments has been implemented.

 \section{Performance}\label{sec:performance}
 
-Lorem Ipsum.
+Although high performance was not a primary goal of this work, the resulting performance degradation by intercepting and manipulation should not be too excessive.
+The following two subsections test the performance degradation of \texttt{intercept.so} compared to running a program without any intercepting or hooking.
