High Bandwidth Consumption

Hi

I use ATS 4.2.1 configured as Forward Cache.

I have 60 Mbps consumption without ATS, but with ATS my consumption
increase to 80-90 Mbps.

My installation


Internet - Router - PPPoE Concentrator + Bandwidth Control

My ATS is connect with Router and i use a policy-based routing to
redirect http packets to ATS.

Thanx

Luís Antonio Pereira

Well, that’s borderline disabling it. Maybe just disable it completely? :)

I guess this does make sense if you have a lot of content which is cacheable, but not frequently fetched by more than one (or a small number of) users.

IMHO it's the background fill feature to be blamed for excessive uplink
utilisation in forwarding mode.

While I couldn't find a way to completely disable it, I managed to
drastically reduce my bandwidth overhead by adjusting the following options
in ATS 5.0.0:
CONFIG proxy.config.http.background_fill_active_timeout INT 1
CONFIG proxy.config.http.background_fill_completed_threshold FLOAT 0.999999

HTH,
Niki
