Since about 3 months i am running a small middle relay with Advertised Bandwidth of 1 MB/s.

The ISP cuts the line every night as its common on most German private DSL. The relay therefore doesn't get a stable-flag :-(

What is the amount of traffic i could/should possibly generate?

Is a utilization between 10 and 20 percent not too small, with 15% RAM, 0-20% CPU used only?

Could i do any better?

Rgds
