how to increase serpattacks speed?

I've just started using serpattacks as a keyword tool to research for competitors for specific long tail keywords but it seems like the speed is wayy too slow for it to be useful. Even after adding proxies it's still really slow. Is there anyway to increase the speed? Or can anyone recommended a service similar that is quick? I'm not looking for a lot of features, just something to compare competition for certain keywords


Thanks guys

proxy slows down the process lol, if you want to speed up, close all running threads (mostly internet browsers, seo softwares, etc.)
