\caption{$\tilde{t}_{lat}$ [\SI{}{\micro\second}] as reported by \texttt{ib\_send\_lat} for different service types and message sizes with a varying \gls{mtu}. All communication went over an \gls{rdma} \gls{cm} \gls{qp} and was sent with the normal \textit{send} operation. Every test contained 1000 iterations and messages that were smaller than \SI{188}{\byte} were sent inline.}\label{tab:mtu_performance}
