Life on the Edge: Monitoring and Running a Very Large Perforce Installation.
Dan Bloch · 2007
Although Perforce does a remarkable job of scaling, Google's main server is at the limits of what Perforce can do, and eternal vigilance is the price of being able to provide acceptable service to our users. This talk discusses the monitoring tools and techniques used at Google and the actions that we (or the tools) take in response to the information provided. Some new Perforce features, notably the performance tracking information introduced in Perforce 2005.2, are discussed in detail. A key result which applies to smaller sites is that server load is often caused by a few users or a few commands, and the ability to identify these allows improvement to performance without the purchase of additional hardware or software.
