 As expected, DRAMSys outperforms the gem5 full-system and syscall-emulation simulators in every case.
 On average, DRAMSys is 47.0\% faster than gem5 SE and 73.7\% faster than gem5 FS, with a maximum speedup of 82.6\% for the benchmark \texttt{SUM}.
 While gem5 SE only simulates the target application using the detailed processor model, gem5 FS has to simulate the complete operating system kernel and applications, that run in the background concurrently.
+This explains the large runtime differences between these two simulation modes.
