Hi guys! I'm considering to purchase this servise, but it worries me that it might slow my site down. Did any of you try it? They say it doesn't slow down the site's loading time because their script loads in parallel to the site's HTML, and I don't understant it enough to know if it makes sense. The tool: vwo (.) com The page in which they're explaining about asynchronous code: vwo (.) com/knowledge/advantages-of-asynchronous-code/ (For some reasom it didn't let me post the links, not sure why. If it's forbidden, please let me know) Any help would be appreciated.
