I hear my users constantly yelling for more features. Not one has complained about the page load (5mb uncompressed, plus a delay for auth to initialize).
I'll keep listening to my users.

Except on forum's. We complain there :P
On the other hand, Gmail regularly takes 10s+ to load and yet most users are glued to it.
If you're a SaaS business, your marketing page is probably not your app. The people using your app care about usability, and page load speed is rarely the driving factor. Especially with SPAs.
Better yet, ask your actual customers.
What I've found is that the users I have that complain are by far the minority of my users. They ask for every little whim, many of them conflicting. If I'd been listening to them my website would be a mess right now. Alexa top 5k. 7 million uniques / day. 550kb. Less than 2 years old.
Every time I implement a new feature, there is no significant change in my site's trajectory. Improving latency by adding an auto-scaler, however, has lead to a massive uptick in usage in the past 90 days.
