Sorry for the dumb question, but why do you want to do those
operations in parallel? The SuperServer runs only one thread at a
time, ties a connection to an thread, and uses only one processor. Do
you think it will be faster interweaving n commands than running the
operations sequentially? And of course, the classic architecture has
the same general limitations, except there is a process per
connection.

No.

Good luck,
