"Mutation" isn't really a descriptive name for these tests as they're specifically testing the performance of mutation observers.
Can it be PerformanceTests/DOM/MutationObserver ?
Either of the proposed names sounds good to me.
(In reply to comment #1) > Can it be PerformanceTests/DOM/MutationObserver ? Yeah. That's more pleasing to eyes but I don't think we normally use CamelCase for subdirectories though. e.g. we have "resources" directories instead of "Resources", and WebCore/editing instead of WebCore/Editing.
I prefer camelcase style, but what is our conclusion now?
(In reply to comment #4) > I prefer camelcase style, but what is our conclusion now? We should probably just use CamelCase. On somewhat related note, I don't think we should have nested directory structures in PerformanceTests if we wanted to use Datazilla (Mozilla's new perf-o-matic).
