How do you scale your ActiveMQ vertically?

Can anyone share experiences regarding ActiveMQ vertical scaling? I am particularly interested in how performance affects:

• NIO Transport
• org.apache.activemq.UseDedicatedTaskRunner option
• disabling hard coding in OpenWire
• using various types of message stores (including KahaDB)
