How to reduce spacing between the rows in the latex longtable

Question

Hello I am having this code that results in the multiple page longtable generation. However, I wish to reduce the spacing between the row a bit, without compromising the font of the letters. I tried couple of options that are commented in my code. Does anyone know how to achieve it?

\begin{center}
\begin{longtable}{c c c} 
\caption{A simple longtable example} 
\label{tab:61_analogs}
%\setlength{\tabcolsep}{6pt}\\
%\renewcommand{\arraystretch}{0.1}\\
%\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}\\
\hline
\textbf{Compound ID} & \textbf{Second entry} & \textbf{Third entry} \
\hline
\endfirsthead
\multicolumn{3}{c}%
{\tablename\ \thetable\ -- \textit{Continued from previous page}} \
\hline
\textbf{Compound ID} & \textbf{Second entry} & \textbf{Third entry} \
\hline
\endhead
\hline \multicolumn{3}{r}{\textit{Continued on next page}} \
\endfoot
\hline
