    484 Table \ref{table:mem-benchmark-figs} shows the list of figures that contain memory benchmark results.
    485 
    486485Each figure has 2 graphs, one for each experiment environment.
    487 Each graph has following 5 subgraphs that show program's memory usage and statistics throughout the program lifetime.
    488 
     486Each graph has following 5 subgraphs that show memory usage and statistics throughout the micro-benchmark's lifetime.
    489487\begin{itemize}
    490488\item \textit{\textbf{current\_req\_mem(B)}} shows the amount of dynamic memory requested and currently in-use of the benchmark.
    491 \item \textit{\textbf{heap}}* shows the memory requested by the program (allocator) from the system that lies in the heap area.
    492 \item \textit{\textbf{mmap\_so}}* shows the memory requested by the program (allocator) from the system that lies in the mmap area.
    493 \item \textit{\textbf{mmap}}* shows the memory requested by the program (allocator or shared libraries) from the system that lies in the mmap area.
    494 \item \textit{\textbf{total\_dynamic}} shows the total usage of dynamic memory by the benchmark program which is a sum of heap, mmap, and mmap\_so.
     489\item \textit{\textbf{heap}}* shows the memory requested by the program (allocator) from the system that lies in the heap (@sbrk@) area.
     490\item \textit{\textbf{mmap\_so}}* shows the memory requested by the program (allocator) from the system that lies in the @mmap@ area.
     491\item \textit{\textbf{mmap}}* shows the memory requested by the program (allocator or shared libraries) from the system that lies in the @mmap@ area.
     492\item \textit{\textbf{total\_dynamic}} shows the total usage of dynamic memory by the benchmark program, which is a sum of \textit{heap}, \textit{mmap}, and \textit{mmap\_so}.
    495493\end{itemize}
    496 
    497 * These statistics are gathered by monitoring the \textit{/proc/self/maps} file of the process in linux system.
    498 
    499 For each subgraph, x-axis shows the time during the program lifetime at which the data point was generated.
    500 Y-axis shows the memory usage in bytes.
    501 
    502 For the experiment, at a certain time in the program's life, the difference between the memory requested by the benchmark (\textit{current\_req\_mem(B)})
    503 and the memory that the process has received from system (\textit{heap}, \textit{mmap}) should be minimum.
     494* These statistics are gathered by monitoring a process's @/proc/self/maps@ file.
     495
     496The X-axis shows the time when the memory information is polled.
     497The Y-axis shows the memory usage in bytes.
     498
     499For the experiment, at a certain time in the program's life, the difference between the memory requested by the benchmark (\textit{current\_req\_mem(B)}) and the memory that the process has received from system (\textit{heap}, \textit{mmap}) should be minimum.
    504500This difference is the memory overhead caused by the allocator and shows the level of fragmentation in the allocator.
     501
     502First, the differences in the shape of the curves between architectures (top ARM, bottom x64) is small, where the differences are in the amount of memory used.
     503Hence, it is possible to focus on either the top or bottom graph.
     504The heap curve It is possible glib, hoard, jemalloc, ptmalloc3, rpmalloc do not use the sbrk area => only uses mmap.
     505
     506hoard, tbbmalloc uses more total memory
     507
     508ptmalloc3 gives memory back to operating system
