有个用于测试 HTTPS 链接各阶段耗时的命令行工具想不起来叫啥了

[isbase]

用法类似 curl https://example.com

它可以输出请求到响应各阶段的耗时，包括 DNS 解析、TLS 握手、等信息

[Livid]

curl -o /dev/null -s -w " \
namelookup: %{time_namelookup}\n \
connect: %{time_connect}\n \
appconnect: %{time_appconnect}\n \
pretransfer: %{time_pretransfer}\n \
redirect: %{time_redirect}\n \
starttransfer: %{time_starttransfer}\n \
total: %{time_total}\n" \

curl -X GET -v "https://www.baidu.cn/" -H "accept: */*" -w "\n"DNS 时间:"%{time_namelookup}\n"到握手时间:"%{time_connect}\n"握手时间:"%{time_appconnect}\n"re 时间:"%{time_redirect}\n"到即将传输开始时间:"%{time_pretransfer}\n"到传输第一个字节时间"%{time_starttransfer}\n"总时间:"%{time_total}\n"下载速度:"%{speed_download}"Bps"\n"下载总量:"%{size_download}"B"\n"
