| The ''perf data'' command allows a perf.data file to be converted to other file formats, however, currently only CTF is supported. This project will look to add support for other file formats such as Firefox's [[https://github.com/firefox-devtools/profiler/blob/main/docs-developer/gecko-profile-format.md|Gecko profile format]] or Chrome's [[https://docs.google.com/document/d/1CvAClvFfyA5R-PhYUmn5OOQtYMH4h6I0nSsKchNAySU/preview|trace event format]]. By supporting conversion to these file formats visualization tools will be able to show a recorded perf.data file. | The ''perf data'' command allows a perf.data file to be converted to other file formats, however, currently only CTF is supported.

| + | ==== Scalability and speed ==== | ||
| + | |||
| + | Large parts of the perf command are single threaded. As CPU core counts increase, this means that programming events can be slow and the command in general can be slower that it needs to be. This project will look to provide parallel approaches to processing perf data structures such as ''evlist'' so that more concurrency happens within the perf command. | ||
