\chapter{Results and Discussion}
The two tables \ref{t:effectivity}, \ref{t:efficiency} contain raw measurement values for the two goals, described in \ref{k5:goals}. The first table visualizes how long each compression procedure took, in milliseconds. The second one contains file sizes in bytes. Each row contains information about one of the \texttt{Homo\_sapiens.GRCh38.dna.chromosome.}x\texttt{.fa} files. To improve readability, the filename in all tables were replaced by \texttt{File}. To determine which file was compressed, simply replace the placeholder with the number following \texttt{File}.\\

The units milliseconds and bytes store a high persicion for measurements. Unfortunally they are harder to read and compare to the human eye. Therefore, starting with comparing sizes, \ref{t:sizepercent} contian the percentual size of each file in relation to the respective source file. The compression with \acs{GeCo} with the file Homo\_sapiens.GRCh38.dna.chromosome.11.fa resulted in a file that were only 17.6\% as big.\\

Overall, Samtools \acs{BAM} resulted in 71.76\% size reduction, the \acs{CRAM} methode improved this by rughly 2.5\%. \acs{GeCo} provided the greatest reduction with 78.53\%. This gap of about 4\% comes with a comparatively great sacrifice in time.\\

As \ref{t:time} is showing, the average compression duration for \acs{GeCo} is at 42.57s. That is a little over 33s, or 78\% longer than the average runtime of samtools for compressing into the \acs{CRAM} format.\\
Before interpreting this data further, a quick view into development processes: \acs{GeCo} stopped development in the year 2016 while Samtools is being developed since 2015, to this day, with over 70 people contributing. Considering the data with that in mind, an improvement in \acs{GeCo}s efficiency, would be a start to equalize the great gap in the compression duration.\\
