Triage Process

The goals of the triage process are:

• determine if the bug is a performance issue
• assign a priority using the performance flag
• assign appropriate keywords
• move the bug to the most suitable component

The calculator is a good way to find the right priority.

Sometimes the information isn't enough to make a decision, in that case we can "need info" the reporter asking for more data, for example an export of `about:support` or a performance profile, or simply more information about the steps to reproduce.
