RabbitMQ should be able to handle 20k messages without any troubles.
But as all the messages are stored in memroy, please make sure that
you have enough RAM+swap available.

You also should make sure that the messages are relatively small.

If you want to handle even more data in queues, you could use our experimental
code. In one of our development code branches we try to make rabbit dump queues
to the disk, when it's running short of memory.

Hope that helps.
