[FOSDEM] Call for participation: Software Performance Devroom - FOSDEM 2026

[zamazan4ik]

Hello!

We are delighted to announce the Call for Participation for the "Software
Performance" devroom at FOSDEM 2026!
This is our first time doing this devroom, so let's make it interesting for
everyone together!


About the devroom
===============

Software Performance is a huge and important topic nowadays: it shapes user
experience, infrastructure cost, scalability, and even sustainability.
Yet, every open source project tackles performance in its own way: through
tools, methodologies, trade-offs, and practices.

This devroom aims to create a space for cross-project collaboration and
experience exchange in the field of software performance.
We want to bring together contributors from different ecosystems to share
how they measure, optimize, and sustain performance in open source.

The devroom’s goal is to:

* Foster knowledge sharing between open source communities tackling
performance challenges.
* Highlight success stories and lessons learned in improving performance
across different open source projects.
* Connect people who care about performance - whether in compilers,
databases, operating systems, or any other software domain.


Submission
==============

Please submit your proposal through the FOSDEM pretalx interface <
https://fosdem.org/submit>, clicking the “Submit a proposal” button.

Please make sure you select “Software Performance” as the "Track”.

By default, we will assume you submit a proposal for a full talk, aiming
for 25 minutes of presenting and 5 minutes of questions.
If you propose a different kind of talk and would prefer a different
length, please do clearly state so in the “Submission Notes” field.
We optimize the length of individual presentations, taking into account all
submissions and preferred length to achieve the best possible overall
program.

Presentations will be recorded and streamed. Sending your proposal implies
giving permission to be recorded.

This year, FOSDEM only accepts in-person presentations, with a live stream
and live chat for remote participants.

The deadline for receiving proposals is November 30th, 2025.
Speakers will be notified of acceptance or rejection by December 15th.


Suggested Topics
==============

Software performance is a huge topic, and it can be viewed from different
and diverse perspectives:

* CPU/GPU throughput/latency
* memory consumption
* energy efficiency
* I/O performance
* etc.

We are interested in all of them!

We invite proposals on any aspect of software performance in open source,
especially those that share practical experience or cross-community
insights,
such as (but not limited to):

* Real-world performance case studies in open source: what worked, what
didn’t, and why (like CachyOS performance-oriented developments)
* Interesting performance challenges and developments from open source
projects (e.g. network stack optimization from the Linux kernel)
* Performance governance in open source communities (processes, culture,
sustainability)
* Performance documentation and education initiatives (like FFmpeg Assembly
Language Lessons)
* Whatever else you think is important for open source performance!

Talks involving performance developments across project or domain
boundaries are strongly encouraged.
If you are not sure whether your topic is suitable or not, don’t hesitate
to send it!


Important Dates
==============

* November 30th 2025: Deadline for submission of proposals
* December 15th 2025: Announcement of acceptance + final schedule
* February 1st 2026: Devroom day, in-person in Brussels.


Volunteers
==============

We will also call for volunteers to help us run the event and help us with
the devroom operation.
Please email the organizers, in case you are interested.
