\section{Experimental Setup}
|
|
|
|
%% ============================================================================
|
|
|
|
\subsection{Hardware}
|
|
|
|
All experiments use identical bare-metal nodes:
|
|
|
|
\begin{table}[h]
|
|
\centering
|
|
\begin{tabular}{@{}ll@{}}
|
|
\toprule
|
|
\textbf{Component} & \textbf{Specification} \\
|
|
\midrule
|
|
CPU & AMD EPYC 9454 (48 cores, 2.75\,GHz) \\
|
|
RAM & 256\,GB DDR5-4800 ECC \\
|
|
Storage & 2$\times$ 3.84\,TB NVMe Gen5 (RAID~0) \\
|
|
Network & 25\,Gbps bonded Ethernet \\
|
|
OS & Ubuntu 24.04 LTS, kernel 6.8 \\
|

\end{tabular}

\label{tab:hardware}
|
|
\end{table}
|
|
|
|
\subsection{Geographic Distribution}
|
|
|
|
Three datacenters provide realistic WAN conditions:
|
|
|
|
\begin{table}[h]
|
|
\centering
|
|
\begin{tabular}{@{}llll@{}}
|
|
\toprule
|
|
\textbf{Site} & \textbf{Location} & \textbf{RTT to SFO} & \textbf{RTT to NYC} \\
|
|
\midrule
|
|
SFO & San Francisco, CA & --- & 62\,ms \\
|
|
NYC & New York, NY & 62\,ms & --- \\
|
|
MCI & Kansas City, MO & 38\,ms & 28\,ms \\
|
|
\bottomrule
|
|
\end{tabular}
|
|
\caption{Inter-datacenter round-trip latencies (measured via ICMP, median of 10{,}000 samples).}
|
|
\label{tab:latency}
|
|
\end{table}
|
|
|
|
Validators are distributed equally across all three sites (e.g., 7/7/7 for $n=21$,
|
|
34/33/33 for $n=100$).
|
|
|
|
\subsection{Methodology}
|
|
|
|
\begin{itemize}
|
|
\item \textbf{Warm-up}: 60\,s of sustained load before measurement begins.
|
|
\item \textbf{Duration}: Each test runs for 300\,s (5\,min) of steady-state operation.
|
|
\item \textbf{Repetitions}: 10 independent runs per configuration. We report median
|
|
and p99 values.
|
|
\item \textbf{Load generation}: Dedicated client nodes (not validators) inject
|
|
transactions at increasing rates until saturation.
|
|
\item \textbf{Finality measurement}: Wall-clock time from transaction submission to
|
|
irreversible commitment, measured at the client.
|
|
\item \textbf{Software versions}: Quasar v1.4.0, CometBFT v0.38.15, aptos-core v1.18,
|
|
sui v1.36, Lighthouse v5.3, Agave v2.0, AvalancheGo v1.11.12.
|
|
\end{itemize}
