       | Well, the author's investigation was involved, although it seems
       | like a labour of love, and I enjoyed reading it.
       | 
       | If benchmarking 28 vs 32 didn't yield an obvious result, lazier
       | old me, if I'd even been benchmarking at all, might have tried
       | more data points, hoping to reveal a trend line that points to
       | somewhere interesting e.g. 16, 17, 18, 19, 20, 21, 22, 23, 24,
       | 25, 26, 27, 28, 29, 30, 31, 32.

       | This was fascinating. If any Go compiler experts happen to read
       | this and know why `Entry{}` was copied on the stack before being
       | copied into the buffer, I think that would be cool to read and
       | tie off this article nicely

       | Storj DCS is a great tool. So obvious that decentralized storage
       | beats Amazon S3 in price, performance, and security

         | Why would that be obvious? Decentralized means losing economies
         | of scale - you can't buy 10k drives at a time from the
         | manufacturer, you run on random hardware builds, you pay to run
         | machines on lower-efficiency PSUs, and you have to compensate
         | for worse uptime per node. Where is it winning?

           | Decentralized storage taps into latent/underutilized capacity
           | from datacenters and individuals across the world. For
           | example, if you have 10TBs of free capacity that wouldn't
           | otherwise be used, and running a node is pure margin. Most
           | private datacenters are at about 40% capacity.
           | 
           | Another example -> the total cost for me is more than 10x
           | cheaper than AWS - its 7$ for TB/Bandwidth vs $90 on AWS. I
           | can also get 1.8gbps - in my region, which is even faster
           | than AWS, and it doesn't rely on ACL databases (it uses
           | client-side hmacs for file authorization). So, for my use
           | case (static content storage and low-volume CDN usage)
           | decentralized cloud wins. (it's 10x cheaper, faster, and more
           | secure for my needs).

       | Love Storj...concept and execution are done extremely well.
