(in a sense a fast performance regression test). You have to be specific about what you're measuring, because "performance" is vague. You can measure many aspects of blockchain performance by importing blocks via -loadblock=FILE. Other performance measurements like "how fast does a block relay through the network" cannot be as easily measured. -- Jeff Garzik exMULTI, Inc. jgarzik@exmulti.com
