A clone is a clone. The main inplementation difference between a thread and process in Linux is COW, for all intensive purposes a worker process and a fork are the same in this use case. Neither have led to scalable web servers.

Except you are basing yourself on the fact it creates a single worker process per connection. It does not.

Workers are spawned when the server is started. Each of them deals with tens of thousands of connections on its own via the listening socket they share.

This is a common technique and scales incredible well.
