How many users would the serve?

The number of requests able to be served could depend on the bandwidth of the machine, and it could depend on the file system. If a web object is 50KB compressed, and served compressed, then with 2Gbits/second, we could serve a maximum of 5,000 per second based on bandwidth. If each hard drive is about 200 seeks per second, and a retrieval is four seeks on average (this is an estimate), then with 36 hard drives, that would be 1,800 retrieves per second. If there were popular pages, these would stay in ram or an SSD, so it could be even quite faster. But assuming 1,800 per second, this would be about 700Mbits/sec which is not stretching the proposed machines. Therefore:

* 1,800 “Here is the web object” requests processed per second maximum.

To make a guess, maybe we could use the use of mobile devices telemarketing data use of web servers. At least in my family, the web use is a small percentage of the total traffic, and even the sites that are used are unlikely to be decentralized websites (like YouTube). So if a user uses 1GByte per month on web traffic, and 5% of those are decentralized websites, so 50MB/month per user of decentralized websites could give an estimate. If the server can serve at 700Mbits/sec, then that is 226Terabytes/month. At at the 50MB usage that would be over 4 million users. Therefore:

* Over 4 million users can be served from that single server (again, a guess.)

So, by this argument, a single Decentralized Web Server can serve a million websites to 4 million users and cost $14,000. Even if it does not perform this well, this could work well for quite a while.

Obviously, we do not want just one Decentralized Web Server, but it is interesting to know that one computer could serve the whole system during early stages, and then more can be added at any time. If there were more, then the system would be more robust, could scale to larger amounts of data, could serve users faster because the content could be brought closer to users.

Performance and cost do not seem to be a problem—in fact, there may be an advantage to the decentralized web over current web server technology.
