Radenku.com – Iperf3 adalah alat untuk mengukur bandwidth dan kecepatan suatu jaringan. Iperf3 mendukung TCP, UDP, SCTP with IPv4 and IPv6. Dengan iperf3 bisa mengukur kecepatan maksimal suatu koneksi jaringan, router, kabel LAN, USB to LAN, dll. Iperf3 berguna untuk mengukur throughput maksimum sebuah jaringan. Tutorial dan cara menggunakan iperf3 seperti berikut.
1. Install iperf3
Install iperf3 Openwrt
Iperf3 openwrt bisa bisa diinstall langsung menggunakan opkg, bisa menggunakan LuCI atau Terminal, jika menggunakan terminal bisa menggunakan perintah
opkg install iperf3
Install iperf3 Debian/Ubuntu
Untuk iperf3 debian dan ubuntu, contohnya ini aku install iperf3 raspberry pi 4.
sudo apt install iperf3
Install iperf3 Windows
Iperf3 download versi Windows bisa diunduh di web iperf3. Unzip iperf dan menggunakannya lewat Command Prompt atau Power Shells.
Install iperf3 Android
Untuk iperf3 android bisa menggunakan Magic iPerf atau he.net – Network Tools di playstore.
2. Cara Tes Kecepatan Menggunakan Iperf3
Untuk cara menggunakan iperf3 openwrt & windows harus diinstall dan dijalankan di kedua sisi baik server dan client.
Iperf3 Server
Untuk di server yang akan kita tes menggunakan iperf3 command iperf3 -s. Iperf3 server akan jalan di port default 5201.
iperf3 -s
Server akan standby menunggu sisi client dijalankan. Biarkan terminal terbuka, jangan di close. Tinggal lanjut masuk ke terminal sisi client.
Iperf3 Client
Untuk sisi client harus terhubung dengan server baik itu melalui Wifi, LAN, ataupun internet yang pasti kita tahu alamat IP server.
Tinggal jalankan iperf3 command iperf3 -c <ip-server-iperf3>.
Contoh dibawah iperf3 yang yg running di routerku dengan IP 10.10.1.1, bisa sesuaikan dengan IP server kalian misalnya 192.168.1.1 dll.
iperf3 -c 10.10.1.1
Iperf3 akan menjalankan tes speed. Output hasil tes akan tampil disisi client dan server.
3. Sample Iperf3 Speed Test
Dibawah beberapa sample iperf3 speed test menggunakan beberapa router, USB to LAN dan Wifi.
Untuk iperf3 bandwidth test menggunakan router Glinet B1300 yang mempunyai gigabit ethernet. Glinet B1300 disambungkan dengan LAN dengan Gigabit USB to LAN TP Link ue300 ke laptop.
Disini aku coba iperf3 throughput test ke laptop di USB 2.0 dan USB 3.0. Karena secara teori USB 2.0 bisa membawa bandwidth 480 Mbps & USB 3.0 sampai 5Gbps, jika dilakukan network speed test maka speed akan mentok disitu.
Untuk hasilnya bisa disimak berikut
Glinet B1300 > TP Link UE300 USB to LAN > Laptop USB 3.0

Selain menggunakan kabel LAN aku juga mengetes speed test wifi dari Glinet B1300 menggunakan HP Poco X3. Untuk iperf3 maximum bandwidth wifi di 2.4Ghz di angka 73-100Mbps dan di 5Ghz diantara 300-330Mbps.
Jadi jika speed test internet kalian dibawah 70Mbps maka bisa jadi karena bottle neck pada router wifi 2.4Ghz, dan mungkin perlu dipertimbangkan untuk upgrade dengan router support Wifi 5Ghz ac atau bahkan wifi 6 ax.

Glinet B1300 > Wifi 5 GHz 80Mhz > Poco X3 NFC
4. Tes Performa Raw Router
Iperf3 juga bisa tes network performance internal raw CPU router, bisa di cek menggunakan perintah
iperf3 -s -D && iperf3 -c 127.0.0.1
