That’s curious. In looking at the Pingdom results you posted, it seems that the pageload problems are coming from slow server response times on other assets, not the Lazy Load scripts.
On the first test you posted (https://tools.pingdom.com/fpt/#!/eEEiZT/https://fpv.tv/hubsan-h501s-x4-fpv-quadcopter-with-gps-osd-follow-me-and-1080p-camera/) the files that are responsible for the slow load times are several of your theme css files and the sabai plugin css. This plugin doesn’t interfere with the stylesheets that are being loaded.
In the second test (https://tools.pingdom.com/fpt/#!/eqtKX8/https://fpv.tv/hubsan-h501s-x4-fpv-quadcopter-with-gps-osd-follow-me-and-1080p-camera/) the slow response times are from a dozen-or-so .jpgs.
Regardless, nothing in the tests you posted indicates anything that would suggest my plugin is slowing things down. This is quite perplexing. I’m not sure what to make of it.
I tested your site myself a few times, and it took approximately 10-15 seconds to load each time (and the plugin is still deactivated, as far as I can tell). I suspect that your issue is actually a server problem, and it’s just a coincidence that it loaded quickly on pingdom with my plugin installed.
It’s hard to say for sure, but that’s my best guess. You’re also making an extraordinarily high number of http requests (~140). I’d recommend also installing a plugin like Autoptimize to combine and minify your JS/CSS. That, in combination with the lazy-load plugin, ought to significantly cut your pageload time.
ecograder.com would also be a helpful evaluation tool.
Sorry I couldn’t provide a more concrete answer, but I’m not convinced based on what I’m seeing here that this plugin is the issue (though I’m not entirely ruling it out).
