What is different between the actor model and seda model?

问题

Talk about your understanding, what is different between the actor model and this seda stage model .

The actor model have the mailbox ,and the seda stage have a job list.
Then the seda stage have an single threadpool, but all stage can share an single threadpool. The actor model all actors share an single threadPool .

I think them essential equivalent.
