      # 修改了 max-connection-per-server from 16 to 128,
# 参考： https://ntsd.dev/aria2-max-connections-per-server/
brew tap xhsgg12302/aria2 https://github.com/xhsgg12302/aria2.git
brew extract --version 1.36.0 aria2 xhsgg12302/aria2
# tar -czvf aria2.tar.gz aria2
# readlink -f aria2.tar.gz
# 计算sha256值
shasum -a 256 aria2-1.36.0.tar.xz
brew install xhsgg12302/aria2/aria2@1.36.0 --verbose --debug --build-from-source

# 使用原生的下载,即使使用128个单机并发，最多16个连接数
/usr/local/Cellar/aria2/1.36.0_2/bin/aria2c -s128 -k20M https://releases.ubuntu.com/22.04/ubuntu-22.04.2-desktop-amd64.iso
# 但是使用重新编译过后的,最大连接数可以达到128，至于速度问题，可能和当前网络环境，以及服务器带宽有关系。
# 这种针对服务器网络单个连接差的很有效。多起线程，聚少成多。
