Earlier today I uploaded a huge list of sites (which I know use SB) to the Back Link checker, to obviously harvest a list for me to target. The total amount of URLs added was over 400,000 and I let it ran for an hour or so before stopping it and selecting 'Download All'. Almost 2 hours later and it's not yet created the file - is this normal? Can it take hours for SB to get the txt file with all the backlinks, if this runs into 100,000s or even millions? Or will it just 'hang'? It's only 1gb Ram and has Tweet Adder also running, so my first thoughts is that it will work, it will just take quite a while, due to the huge amount of URLs it's dealing with.
