Re: Which scales better? J2EE, PHP, or CGIDEV2?

Yes they do. Some of the app servers (Jetty for sure) also manage connections the same way i manages jobs (i.e., requests that are waiting for backend I/O are shuffled off to a separate pool and the sockets are reused for other requests). This allows concurrent requests to scale beyond the number of TCP/IP ports available.

I would be curious to know how much CPU time is required to
create a new J2EE thread ...

I answered hastily the last time. Instantiating a Thread in Java is trivial,
but depending on what else may be instantiated from within a Thread, it could
get expensive. I don't know what might get instantiated from within JEE server
threads. But it would make a lot more sense to reuse a pool of threads for
incoming browser requests, which is what app servers do, according to Thor. So
the question is probably moot.
