In bug 1256408 I've landed code to allow adding *in-tree* platform micro-benchmarks for XUL code in less than 10 lines. These are just GTest where the execution time is reported to perfherder. This makes it easy to add low level platform micro-benchmarks for testing things that Talos is not well suited for. Maybe a bit too easy in fact so please keep in mind that there is a cost to collecting perf data and particularly monitoring the alerts so try to use sparingly.
You can find more information on this here: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/GTest#MozGTestBench A big caveat is that we're rolling this out, at the moment, as part of the GTest job which doesn't run on a stable hardware configuration like the Talos job. If the results are too noisy we might look into fixing this. However since we're running micro-benchmarks we also lose a lot of the noise that Talos has to deal with like the event queue, GC, paint scheduling etc... Here's an example of micro-benchmarks for nsRegion And()/Or() performance which is critical for layout and graphics performance and basic headless compositing: https://treeherder.allizom.org/perf.html#/graphs?series=%5Bmozilla-inbound,db7b8908a950b105f475ead838f8f472c89b20ad,1%5D&series=%5Bmozilla-inbound,ad41ac00e3191623cd89ed0c7df7464a5faf86c2,1%5D&series=%5Bmozilla-inbound,feded2f5510c634c95b0810fb35e7f633ffa6443,1%5D <https://treeherder.allizom.org/perf.html#/graphs?series=%5Btry,ad41ac00e3191623cd89ed0c7df7464a5faf86c2,1%5D&selected=%5Btry,ad41ac00e3191623cd89ed0c7df7464a5faf86c2,69922,18676584%5D> <https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/GTest#MozGTestBench> Alert will be posted here [1]. I should mention that micro-benchmark regressions shouldn't and wont be treated the same way a Talos regression.
