Performance
Mozilla's performance program focuses on improvements to the Gecko platform and the Firefox Desktop and Firefox for Android products.
Projects
Active
"Cold" page load benchmark
| Product impact | [DESKTOP] [MOBILE] [B2G] |
|---|---|
| Goal | Create a reliable1 Talos benchmark for 'cold' page load times.
1Reliable in this case refers to minimizing variability in the data between runs on the benchmark system. |
| Duration | TBD |
| Team | Nathan Froyd (lead), Avi Halachmi |
| Progress reports | TeamStatus: Nathan Froyd, Avi Halachmi |
| Work | |
| Dependencies | |
| Notes | This project will start by exploring viability of such a benchmark. If the benchmark turns out to be infeasible, we will document the results and move on to another project. |
Incremental Cycle Collection (CC)
| Product impact | [DESKTOP] [MOBILE] [B2G] |
|---|---|
| Goal | Implement incremental cycle collection to reduce1 cycle collector pauses in the Firefox UI.
1Reduction in cycle collector pauses will be measured with the CYCLE_COLLECTOR_FULL Telemetry probe. The degree of reduction that can be achieved is currently unclear. |
| Duration | TBD |
| Team | Andrew McCreight (lead) |
| Progress reports | TeamStatus: Andrew McCreight |
| Work | bug 850065 |
| Dependencies | |
| Notes |
Profiler Backend for Mobile
| Product impact | [MOBILE] [B2G] |
|---|---|
| Goal | Accurate1, crash-free, deadlock-free, low overhead2 stack unwinding for the SPS profiler for Firefox for Android and Firefox OS.
[1]The correct sequence of code return addresses on the stack, ideally without the unwind terminating before it gets back to main(). |
| Duration | TBD |
| Team | Julian Seward (lead), Benoit Girard, Mike Hommey |
