One Page Not Cached

[seofeed]

This is posted over in the S2Member forum. The actual issue is that I have two pages with the exact same content but different buy links. One page has a ton of S2Member buy links and it takes forever to load. I'm guessing its because the link generation is slow.

You can see the performance issues here:

No S2Member links:
http://curationsoft.com/download/

With S2Member links:
http://curationsoft.com/pricing/

The difference is substantial. Anyway, got rid of the W3 Cache plugin except for the CDN section and installed Quick Cache to handle all caching.

Now, the /download page uses Quick Cache and the /pricing page doesn't. I've tried Auto-Caching and everything else is set to default. No clue why Quick Cache wouldn't cache /pricing.

Any clues? I've already tried a bunch of this per this thread:
