For each benchmark we analyze CPU time performing 10 trials preceded by an initial warm-up iteration; reported confidence intervals are stated at 95\% confidence level.  \subsection{Results}  We now present the main results of our experimental evaluation, which are aimed at addressing the following questions:  \begin{description}  \item[Q1] How much does a never-firing OSR point impact code quality?  \item[Q2] What is the overhead of an OSR transition to the same function?  \item[Q3] What is the overhead of the \osrkit\ library for inserting OSR points?  \item[Q4] What kind of benefits can I expect [...]  \end{description}  \begin{itemize}  \item {\bf Message 1}: how much does a never-firing OSR point impact code quality? We run a program with one or more OSR points, and we measure the slowdown given by factors such as cache effects (due to code bloat), register pressure, etc. due to the presence of the OSR points.
