How to benchmark server performance using Speedtest and SysBench
Heads-up: Speedtest is known for tracking users therefore it is recommended to run the following benchmark tests on staging servers.
Requirements
- Virtual private server (VPS) or dedicated server running Debian 10 (buster) or Debian 11 (bullseye)
Caveats
- When copy/pasting commands that start with
$, strip out$as this character is not part of the command - When copy/pasting commands that start with
cat << "EOF", select all lines at once (fromcat << "EOF"toEOFinclusively) as they are part of the same (single) command
Setup guide
Step 1: check if backports repository is enabled
cat /etc/apt/sources.list | grep "backports"
Step 2: enable backports repository (required if previous command returned nothing)
Heads-up: run
cat /etc/debian_versionto find Debian version.
Debian 10 (buster)
cat << "EOF" >> /etc/apt/sources.list
deb http://deb.debian.org/debian buster-backports main
EOF
apt update
Debian 11 (bullseye)
cat << "EOF" >> /etc/apt/sources.list
deb http://deb.debian.org/debian bullseye-backports main
EOF
apt update
Step 3: install apt-transport-https, cURL and GnuPG
apt update
apt install -y apt-transport-https curl gnupg2
Step 4: import Speedtest’s PGP public key
curl -fsSL https://packagecloud.io/ookla/speedtest-cli/gpgkey | gpg --dearmor > /usr/share/keyrings/speedtest-cli.gpg
Step 5: enable Speedtest’s repository
Heads-up: run
cat /etc/debian_versionto find Debian version.
Debian 10 (buster)
echo -e "deb [signed-by=/usr/share/keyrings/speedtest-cli.gpg] https://packagecloud.io/ookla/speedtest-cli/debian/ buster main\ndeb-src [signed-by=/usr/share/keyrings/speedtest-cli.gpg] https://packagecloud.io/ookla/speedtest-cli/debian/ buster main" > /etc/apt/sources.list.d/speedtest-cli.list
apt update
Debian 11 (bullseye)
echo -e "deb [signed-by=/usr/share/keyrings/speedtest-cli.gpg] https://packagecloud.io/ookla/speedtest-cli/debian/ bullseye main\ndeb-src [signed-by=/usr/share/keyrings/speedtest-cli.gpg] https://packagecloud.io/ookla/speedtest-cli/debian/ bullseye main" > /etc/apt/sources.list.d/speedtest-cli.list
apt update
Step 6: install Speedtest and SysBench
apt install -y speedtest sysbench

Usage guide
Benchmark network
Heads-up: depending on iptables or nftables firewall configuration, running following commands may be required.
iptables
iptables -A OUTPUT -p tcp -m tcp --dport 8080 -m state --state NEW -j ACCEPT
ip6tables -A OUTPUT -p tcp -m tcp --dport 8080 -m state --state NEW -j ACCEPT
nftables
Heads-up: replace
firewallif needed (seenft list ruleset).
nft add rule ip firewall output tcp dport http-alt accept
nft add rule ip6 firewall output tcp dport http-alt accept
