Sorry, but that link works perfectly normally for me. Full page loads in 2.35 secs.
The fact the problem is a) intermittent, and b) limited to your system suggests it is a problem either with your pc, your server. or your internet connection. That’s not a particularly memory-hungry page so I can’t see what the problem could be.
Screenshot attached just to confirm I have understood you and am looking at the right page.
