Software performance is one of the important qualities that makes software stand out in a competitive market. However, in earlier work we found that performance bugs take more time to fix, need to be fixed by more experienced developers and require changes to more code than non-performance bugs. In order to be able to improve the resolution of performance bugs, a better understanding is needed of the current practice and shortcomings of reporting, reproducing, tracking and fixing performance

This paper qualitatively studies a random sample of 400 performance and non-performance bug reports of Mozilla Firefox and Google Chrome across four dimensions (Impact, Context, Fix and Fix validation). We found that developers and users face problems in reproducing performance bugs and have to spend more time discussing performance bugs than other kinds of bugs. Sometimes performance regressions are tolerated as a tradeoff to improve something else.
