'Ello, Remember me?

Anyhow, I'm looking to run this again properly. However I'm running it on linux and I want to set it up correctly...

A) I want to limit the bandwidth it uses. Just so it wont use 1Gb a day or something silly.
According to the website it gives me (localhost:1088) it says I've used 47Mb in the 18 minutes I've had this running.
I cant find an option to say crawl 100Mb a day then shutdown, yet I'm sure there was similiar on the windows client.

B) Cant think of anything else at the minute However I'm sure something might come up. I assume bucket size is fixed?
