How to benchmark server performance using Speedtest and SysBench

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 (from cat << "EOF" to EOF inclusively) 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_version to 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_version to 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 firewall if needed (see nft list ruleset).

nft add rule ip firewall output tcp dport http-alt accept
nft add rule ip6 firewall output tcp dport http-alt accept
