# How to benchmark server performance using Speedtest and SysBench [](https://www.youtube.com/watch?v=zcq2iZUcQQY "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 disposable servers. ## Requirements - Virtual private server (VPS) or dedicated server running Debian 10 (buster) ## 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 ```shell cat /etc/apt/sources.list | grep "buster-backports" ``` ### Step 2: enable Backports repository (only run command if previous step returned nothing) ```shell cat << "EOF" >> /etc/apt/sources.list deb http://deb.debian.org/debian buster-backports main EOF apt update ``` ### Step 3: check if GnuPG is installed ```console $ gpg --version -bash: gpg: command not found ``` ### Step 4: install GnuPG (only run command if previous step returned `-bash: gpg: command not found`) ```shell apt update apt install -y gnupg2 ``` ### Step 5: install Common CA certificates ```shell apt install -y ca-certificates ``` ### Step 6: import [Speedtest](https://www.speedtest.net/)’s PGP public key and enable Speedtest’s repository ```console $ apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61 Executing: /tmp/apt-key-gpghome.hyKJZh5s4e/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61 gpg: key 379CE192D401AB61: public key "Bintray (by JFrog) " imported gpg: Total number processed: 1 gpg: imported: 1 $ echo "deb https://ookla.bintray.com/debian buster main" | tee /etc/apt/sources.list.d/speedtest.list deb https://ookla.bintray.com/debian buster main $ apt update ``` ### Step 7: install Speedtest and SysBench ```shell apt install -y speedtest sysbench ``` 👍 --- ## Usage guide ### Benchmark network Depending on iptables configuration, running the following commands may be required. ```shell 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 ``` ```console $ speedtest Speedtest by Ookla Server: Vodafone - Reykjavík (id = 4141) ISP: 1984 ehf Latency: 0.64 ms (0.06 ms jitter) Download: 95.82 Mbps (data used: 158.0 MB) Upload: 95.63 Mbps (data used: 155.7 MB) Packet Loss: 0.0% Result URL: https://www.speedtest.net/result/c/19654353-3d2e-4ed3-ac22-824e1376b838 ``` Network download speed: 95.82 Mbps Network upload speed: 95.63 Mbps 👍 ### Benchmark CPU ```console $ sysbench cpu --cpu-max-prime=20000 run sysbench 1.0.18 (using system LuaJIT 2.1.0-beta3) Running the test with following options: Number of threads: 1 Initializing random number generator from current time Prime numbers limit: 20000 Initializing worker threads...
