I thought it was just trying to load 1gb and I was quite scared.

The cache does no work for me either... Ok, from the comments, it's advocating for 1GB pages at the main memory. Not cache, not disk, not network. Main memory. For me it looks too big - entire servers will have about 32 pages, swapping will take ages at 400MB/s disks. Current PCs use a too small page, but 4MB seems a much more realistic number.

  Often text-only google cache works when normal google cache doesn't. Maybe try that?

  The purpose of 1GB pages is to eliminate TLB pressure for apps that use a lot of RAM, not to swap it out to disk.

  Try the cache text-only: http://webcache.googleusercontent.com/search?q=cache:Frz8FdesJfwJ:www.pvk.ca/Blog/2014/02/18/how-bad-can-1gb-pages-be/&hl=en&gl=us&strip=1 http://webcache.googleusercontent.com/search?q=cache:Frz8Fde...

  The available page sizes are set by the hardware. On x86-64, your current options are 4kB (4-level page tables), 2MB (3-level page tables) and 1GB (2-level page tables).

I'm actually kinda surprised there's no nyud.net-style automatic cache for links posted on Hacker News yet. I'm tempted to buy a cheap used PC and set one up at home... Is there some open source code to implement this aside from curl?

  A reverse proxy that did simple transform on the submission URLs? There are mutating reverse proxy guides all over the net thanks to the UK torrent site blockade.
