For those who live and breathe system performance, the P99 Conference is a must-attend event that dives deep into the art and science of building and scaling high-performance systems. Hosted by ScyllaDB, this virtual conference, scheduled for October 22-23, 2025, is a haven for performance engineers, SREs, developers, and anyone passionate about squeezing every ounce of efficiency from large-scale systems. As Scott Moore, host of the SMC Journal Show, aptly puts it, “If you are a serious performance nerd and you like to hear about how to take systems and scale them out to very, very large sizes,” this is the event for you. Here’s why the P99 Conference stands out and why you should mark your calendar for this unparalleled gathering of performance enthusiasts.
A Deep Dive into Performance Engineering
The P99 Conference is not your average tech event. Unlike conferences focused on broad topics like QA, load testing, or Kubernetes, P99 is laser-focused on the hardcore performance of large-scale systems. Whether you’re optimizing at the code level, tackling latency issues, or architecting systems for massive throughput, P99 offers content that gets “really, really deep, really, really fast.” This is a conference for those who understand the difference between a mean and a percentile and are eager to explore the latest techniques in performance engineering.
The event features an impressive lineup of 36 concurrent tracks, eight keynotes, and 44 scheduled recordings, with an additional 28 “instant access” sessions available for attendees. This vast array of content ensures there’s something for everyone, from intermediate learners to those diving into the most complex, head-spinning technical challenges. Topics span a wide spectrum, including Rust and systems programming, low-latency data and streaming, observability, debugging, testing, and database and storage innovations. With such a diverse range of subjects, P99 caters to performance engineers, developers, and architects alike, blurring the lines between traditional roles in today’s interconnected tech landscape.
Cutting-Edge Topics and Industry Leaders
One of the standout features of P99 is its ability to attract top-tier speakers and cover emerging trends. This year, artificial intelligence (AI) takes center stage, with sessions like Chip Ewen’s presentation on making large language models (LLMs) run fast. Ewen, a former machine learning expert at Nvidia and author of an AI engineering book published by O’Reilly, will share insights into optimizing LLMs—a topic of growing importance as companies scale AI-driven applications. For performance engineers accustomed to testing web applications, this session promises to reveal how to approach the unique challenges of LLMs, often shrouded in secrecy within organizations.
Beyond AI, P99 covers other critical areas. For instance, past conferences have highlighted tools like eBPF, which surprised attendees like Tim Koopmans, a key organizer from ScyllaDB, with its performance monitoring capabilities. This year, expect sessions on database performance, including ScyllaDB’s new vector search feature, as well as innovations from other databases like Turso, Postgres, and Tiger Beetle. The conference also explores serialization protocols, reliability, and even security, ensuring a comprehensive look at the “-ility” words that define modern system design.
What sets P99 apart is its focus on real-world applications at scale. Speakers from both big-name companies and smaller organizations share practical solutions to complex performance problems. As Koopmans notes, “Often the solution is quite straightforward or quite simple, but it’s just done at a scale that we’re not all used to.” This blend of theoretical depth and practical insights makes P99 a goldmine for anyone looking to elevate their performance game.
The Virtual Advantage and Interactive Format
As a virtual conference, P99 offers unparalleled accessibility. Anyone, anywhere can tune in live, making it easy to engage with cutting-edge content without the hassle of travel. The format is designed for interaction, with live chat features that allow attendees to ask questions and even “heckle” speakers in real time, as Koopmans humorously points out. Many session speakers are available during their presentations, fostering direct engagement and creating a dynamic, community-driven experience.
The virtual setup also means you can access a wealth of pre-recorded content, including the 28 “instant access” recordings, giving you flexibility to explore topics at your own pace. Whether you’re joining live or catching up later, P99 ensures you can dive into the sessions that matter most to you.
ScyllaDB’s Role and Database Focus
Hosted by ScyllaDB, a company known for its high-performance database solutions, P99 naturally emphasizes database performance—a critical concern as data lakes, lakehouses, and transaction volumes grow exponentially. Koopmans highlights the challenge: “Most people don’t want to think about the database too much… it’s not a problem until it is, and then suddenly it’s a massive problem.” Sessions will explore how to optimize databases for cost, throughput, and latency, with ScyllaDB showcasing its latest features alongside other innovative databases.
This focus on databases is particularly timely as organizations grapple with scaling data-intensive applications. Whether you’re dealing with massive write throughput or low-latency requirements, P99 offers actionable strategies to address these challenges.
Why You Should Attend
The P99 Conference is a unique opportunity to immerse yourself in the world of high-performance systems. It’s a place where performance nerds can geek out over tail latency, learn from industry leaders, and discover the latest tools and techniques. From AI optimization to database scaling, the conference covers the full spectrum of performance engineering, making it relevant for developers, SREs, and architects alike. The virtual format ensures accessibility, while the interactive elements create a vibrant, engaging experience.
As Koopmans puts it, “If you care about tail latency, if you understand the difference between a mean and a quantile or a percentile, then this conference is for you.” With its blend of technical depth, practical insights, and a passionate community, P99 is arguably the best performance-related conference in its format.
