Someone really needs to call this out properly for the b.s. it is. I had to dd copy very large files that caused the cache to fill up and eat ram, the whole system would come to a crawl. Copy thousands of multu gig files while using firefox, I dare the author! 22GB+ free ram and still can't handle it. It really needs a way to control n% of ram so that absolutley no vfs caching whill happen on that percentage of ram.
