It’s not often that a website stays up mostly unchanged for 25 years. So out of curiosity, I ran a quick check on both sites.
This is keeping with the general trend of websites growing heavier every year, with the average site weighing in at around 1.900KB now.
But since our connection speeds and device capabilities are significantly better now - that’s fine. Everything is way faster now than it was back in the days of Michael Jordan’s first Looney Tunes adventure.
Is it though? Let’s find out.
Party like it’s 1996
1996 was a different time. The Spice Girl’s “Wannabe” was in anti-shock discmans everywhere, and the most common network connection was 56k dial-up modems. So of course the original developers had a smaller performance budget to work with, and the site is much lighter. Fair enough - so how long did it take to load the original Space Jam site back then?
I ran a webpagetest with a simulated '96 connection: dial-up on an average desktop computer. Dial-up had a maximum speed of 56 kbit/s, but in reality it came in at something around 40-50 kbit/s.
Here’s how that looked (fire up the dial-up noise in another tab for the full experience):
We can see the first content (the “press box shuttle” menu item) after 4 seconds. The other menu items -all separate GIF images- come in slowly after that. Since the HTML renders as soon as it is parsed, you could theoretically already click on the items before the rest of the page has finished though. The whole site is done after 28.1 seconds in this test.
Back to the Future: 2021
Now let’s look at the current, futuristic state of the web. Luckily we don’t use dial-up anymore. The most common connection these days is a mobile 3G network, and the most common device is an Android phone (a Moto G4 in this test). A typical 3G connection comes in at around 1.5 Mbp/s, so it is roughly 30 times faster than dial-up. This shouldn’t take long:
Funnily enough, the first meaningful paint also shows up after about 4 seconds. It’s not actual content though, it’s the loading screen, informing us that we’ve now loaded 0% of the site.
We reach 100% at 12 seconds, but the first real piece of content is not rendered until 21.5 seconds: it’s a youtube video in a modal window. The site is finally ready after 26.8 seconds, although actually playing the video would take some more loading time.
Right. So after 25 years of technological progress, after bringing 4.7 billion people in the world online, after we just landed a fifth robot on Mars, visiting the Space Jam website is now 1.3 seconds faster. That seems… underwhelming.
I know that this is just a movie promo site. And of course the requirements for a website are different now - people expect rich content. But I think this speaks to a larger point:
We just keep filling the available space, jamming up the pipes in the process so nothing actually gets faster. Well, at least the dial-up sound is gone now.
