      iTunes 12 is eating 1+ GB of memory. Seriously!? Isn’t a horrible search UX enough? Now you want to eat memory like you were Safari 7?

      @mmunz Yeah, it takes about 150 MB when I launch it and then gradually increases to GBs even if I'm not using it.

      @mjtsai, @mmunz — Why shouldn't an app aggressively cache stuff until your memory is "full"? Why is using otherwise inactive memory bad?

      @simX @mmunz Because it's not otherwise inactive. All of my memory is in use right now.

      @mjtsai, @mmunz — My hunch is yes, Safari and iTunes are pieces of shit, but I remember many complaining about OS X 10.0's "bad" mem usage

      @simX @mmunz Important stuff will get paged in, let it swap out the other stuff. Yet, in practice, rebooting always makes things faster.

          @mjtsai, @mmunz — Point is you want immediate results, so restarting is a nice placebo. But over long term, aggressive caching saves time.

          @simX @mmunz My Mac just "ran out of application memory" because Mail was using 61 GB of Memory (but "only" 3.23 GB of Private Memory).

          @mjtsai @simX @mmunz You ran out of free space on your boot volume?

        6. Michael Tsai ‏@mjtsai 6 Nov 2014

          @rosyna @simX @mmunz Nope, still had 20 GB of space on the SSD, so I'm not sure why the OS decided to pause all my apps.

          @mjtsai Swap file ate up the remaining 20GB? That's how it usually works for me. Some leaky app filling the HD with swap.

        8. Michael Tsai ‏@mjtsai 6 Nov 2014

          @uliwitness Still had 20 GB free with the swap file. Total private memory in use was way less than the physical RAM that I have.

          @mjtsai, @mmunz — Of course it makes things faster, because it clears out all memory so paging stuff in doesn't require paging out to disk.

        2. Michael Tsai ‏@mjtsai 4 Nov 2014

          @simX @mmunz In theory it shouldn't need to page out if there is stuff in RAM that can be purged. Yet in practice it seems to.
