+# Examples
+
+## Test a Http Server
+
+```shell
+# http, 100 concurrency, for 20 seconds
+g3bench h1 http://example.net/echo1k -t 20s -c 100
+# https, 100 concurrency, for 20 seconds
+g3bench h1 https://example.net/echo1k -t 20s -c 100
+# https, no keep-alive, 100 concurrency, for 20 seconds
+g3bench h1 https://example.net/echo1k -t 20s -c 100 --no-keepalive
+# using TLS 1.2 cipher ECDHE-RSA-AES256-GCM-SHA384
+g3bench h1 https://example.net/echo1k -t 20s -c 100 --tls-protocol tls1.2 --tls-ciphers ECDHE-RSA-AES256-GCM-SHA384
+```
+
+## Test a Http Proxy
+
+```shell
+# using HTTP Forward, 100 concurrency, for 20 seconds
+g3bench h1 -x http://192.168.1.1:3128 http://example.net/echo1k -t 20s -c 100
+# using HTTPS Forward, 100 concurrency, for 20 seconds
+g3bench h1 -x http://192.168.1.1:3128 https://example.net/echo1k -t 20s -c 100
+# using HTTP CONNECT, 100 concurrency, for 20 seconds
+g3bench h1 -x http://192.168.1.1:3128 -p https://example.net/echo1k -t 20s -c 100
+# disable HTTP Keep-Alive
+g3bench h1 -x http://192.168.1.1:3128 http://example.net/echo1k --no-keepalive -t 20s -c 100

+
+## Test DNS
+
+```shell
+# DNS over TLS, via Cloudflare Public DNS
+g3bench dns "1.1.1.1" -e dot www.example.com,A --dump-result
+# DNS over HTTPS, via Cloudflare Public DNS
+g3bench dns "1.1.1.1" -e doh www.example.com,A --dump-result
+# DNS over Quic, via AdGuard Public DNS
