Even though it's a meaningless comparison, I'd be interested to see how performance compares (max requests per second?) for this compared to fully-featured web servers.
In a comparison between a similar fork-per-connection server written in C and this, I would imagine the throughput would be about the same, because the bottleneck in this model is fork() itself rather than the actual code. It probably matters more for binary size and startup time than requests/sec. Would be fun to actually benchmark, though.
