[Plugin: WP Super Cache] WP super cache and Google Rank

Hello everybody,
I installed this plugin sucessufully and I have to say that i am happy with it. This plugin is much better than total cache wich screwed my blog and my plugins.

I have only a question:
I installed it because lately on Google Webmaster Tool, Google Bots were taking to much time to crawl my pages.
Will this plugin help decrease the crawling time?

thanks
