This was a disappointing read:

It is an interesting question -- Given actual dropbox usage patterns, is there there an caching approach that is better than LRU for real Dropbox customers?

The answer I got was, hybrid LFU/LRU algorithms could work better, but they are complicated and were never tested against real Dropbox access patterns.




The ARC algorithm is patented (by IBM according to Wikipedia), so that might be why it's not used at least.

He says that he was an intern back in '11. I'm guessing he's full-time now. Not very clear.


He's a junior now :-)
