Is there a way to use the svg package when the subcaption package is included as well? The svg package uses the subfig package, which apparently leads to conflict. But it seems to be common sense that the subcaption package is prefered over the subfig package.

The subfig and subcaption packages can not be used in cooperation with each other. Instead, you can usecaption package with subfig to add some flavor to the captions and subcaptions (or you can use caption along with subcaption (which gives a subfigure command also).
\documentclass{memoir}
\usepackage[demo]{graphicx} % remove [demo] in your file
\usepackage{subfig} % for subfigures
\usepackage{caption}
\usepackage{lipsum}
\captionsetup[figure]{labelfont={bf,small},textfont={it,small}}
\captionsetup[subfloat]{labelfont={bf,small},textfont={it,small},
subrefformat=parens} %<-----designing subcaption
\newcommand{\myfigref}[2]{~\ref{#1}.\subref{#2}}% <---- a new macro for referring to a subfigure

\begin{document}
%=========================
\chapter{First chapter}
\lipsum[1-4]

\begin{figure}[ht]
\includegraphics[width=1\textwidth]{my figure}
\caption{My single picture}\label{fig:figures}
\end{figure}
%=========================
\begin{figure}[ht]
\centering
\subfloat[My first picture]{\label{fig:mdleft}{\includegraphics[width=0.4\textwidth]{my figure}}}\hfill
\subfloat[My second picture]{\label{fig:mdright}{\includegraphics[width=0.4\textwidth]{my figure}}}
\caption{My two big pictures}
\label{fig:subfigures}
\end{figure}
%===========================
From figure~\ref{fig:subfigures}.\subref{fig:mdleft}, we can see a small cat, in
\myfigref{fig:subfigures}{fig:mdright} both can be used to refer figures.

Since sig-alternate defines its own \caption command, the caption package is not really compatible with it; subcaption might work, but the result is not guaranteed. You can do with subfig:
\PassOptionsToPackage{demo}{graphicx} % just for the example
\documentclass{sig-alternate}
\usepackage[caption=false]{subfig}
\usepackage{lipsum} % just for the example
\begin{document}
\lipsum[1-2]
\begin{figure}[ht]
\centering
\subfloat[Comparison one]{%
\includegraphics[width=0.3\textwidth]{figures/fig3}%
\label{Fig:Speed}%
}
\subfloat[Comparison two]{%
\includegraphics[width=0.3\textwidth]{figures/fig3}%
\label{Fig:Time}%
}
\end{figure}
\lipsum
\end{document}
The two lines marked just for the example are for producing the image, don't use them yourself.
Don't use scale=, but prefer setting the width. You should probably use multiples of \columnwidth rather than \textwidth, as the class produces two column documents.

In this answer the solution is to suppress the load of the
subfigpackage by this\expandafter\def\csname ver@subfig.sty\endcsname{}command. Unfortunately, this works for me only until TeX Live 2015.
