Seems like an awesome tool.
As a side note, however, I would recommend anybody to not blindly apply the "Tuning" section (at the bottom of the readme) to their system. More specifically, net.ipv4.tcp_tw_recycle and net.ipv4.tcp_tw_reuse are notorious for causing problems if mis-used.
- oimaz 11y agoCould you elaborate?
- gouggoug 11y agoOf course, net.ipv4.tcp_tw_recycle causes problems with NAT-ed clients. tcp_tw_recycle (Boolean; default: disabled; since Linux 2.4) Enable fast recycling of TIME_WAIT sockets. Enabling this option is not recommended since this causes problems when working with NAT (Network Address Translation). net.ipv4.tcp_tw_reuse seems fine to use, but literature about its real effects is sparse. This link http://vincent.bernat.im/en/blog/2014-tcp-time-wait-state-linux.html http://vincent.bernat.im/en/blog/2014-tcp-time-wait-state-li... mentions both of them.
