If you ever noticed how your SSH/gaming sessions become sluggish when you start downloading something, or how your downloads slow down when you start uploading, and your broadband link is managed by a Linux router/gateway, then you could benefit from using CTShaper. CTShaper reduces link latency by reducing queueing on your side and on your ISP's side. Additionally, it sets up four traffic queues with different priorities and (configurable) flow rates.
