Hey Ben and Hannah.

My website is getting a little slow, and i want to make sure, that the website is as fast as all others out there.
I´ve read the “need for speed” guide, and i have already improved my loading time from 9,50 seconds to 3 seconds. But im still not satisfied, because many other homepages are having a loadtime below 1 second, which is my goal.

I´ve tried to setup some caching by installing WP Super Cache, and i followed a youtube guide for how to set it up, but i still score low in “caching” “Leverage Browser Caching” 29/100. What do I need to do, do score better in caching, besides installing this plugin?

Then i get a score on 0/100 in “Defer parsing of JavaScript”, but i´ve dont know anything about JavaScript and the use of JavaScript on my site is very limited, so I dont really understand how my JavaScript can be that bad for my loading time?

Last, but not least, i get a score of 44/100 in “specify image dimensions”. I´ve uploaded some images with high resolution, like 7000px. But at the time i uploaded the images i didn’t knew about resizing. Now i need to scale down ALL my images on my homepage, (i guess?), because the images are way bigger than whats optimal. Is there an easier way for me to fix this problem, than by manually taking every photo out of WP library, resizing all images 1 by 1 and then upload them to wordpress again?
