The Dark Art of CPU Benchmarking

Benchmarking in Salesforce is an important skill to learn, especially since Salesforce introduced the CPU timeout of ten seconds in the Winter ’14 release. If your code is inefficient, you may start to see exceptions thrown if processing the logic takes longer than the allotted ten seconds (sixty seconds when running asynchronously). Furthermore, other packages running in your Salesforce instance directly impacts all code and declarative functionality – unlike most Salesforce limits, the CPU timeout limit is not unique per namespace. (Also – benchmarking can be fun!)

I was a co-presenter on the topic of CPU benchmarking with Dan Appleman at this year’s Dreamforce conference. Missed the presentation? It was recorded! Check it out below:

The sample code used in the presentation can be found on GitHub at For more information on CPU benchmarking, I encourage you to reference Chapter 3 in Advanced Apex, or search for CPU benchmarking on SearchTheForce.
