P99 CONF is now days away. We’ve already shared a bit about what you can expect, and we’re busy setting the virtual stage for 50+ expert engineers to share innovations, insights, and best practices for lowering latency and optimizing performance from a broad range of perspectives– programming languages, CPUs, front-ends, back-ends, and observability.

To peak pique your interest, let’s hear directly from some of the speakers you can learn from and interact with live on October 19 and 20. What are they most excited to share – and learn?

Roman Gershman, DragonflyDB

Talk: How Dashtable Helps Dragonfly Maintain Low Latency

Why attend your session in 7 words or less?

Learn the art of optimizing hashtable latency.

What other session on the agenda are you most looking forward to and why?

I am interested to listen to “Optimizing Servers for High-Throughput and Low-Latency” by Alexey Ivanov. As backend developers, we strive to build the fastest software possible, but we often neglect the low-hanging fruit – OS configuration. I am always keen to learn up-to-date techniques for fine-tuning the networking stack.

If you have not heard about the dragonfly project, please visit https://github.com/dragonflydb/dragonfly and read our story. Also, I warmly suggest reading our introductory article about DashTable at https://github.com/dragonflydb/dragonfly/blob/main/docs/dashtable.md. It
gives a decent overview of DashTable, and why it is more memory efficient than other approaches.

Talk: How We Reduced Performance Tuning Time by Orders of Magnitude with Database Observability

Why attend your session in 7 words or less?
Tuning database by DB time and color.

What other session on the agenda are you most looking forward to and why?
Gil Tene’s Misery Metrics & Consequences because I’m curious what “misery metrics” means, how to measure them, and how to use them for performance tuning.

1. The two performance tuning methodologies mentioned in my session are “tuning by database time” and “tuning by color”. Our team has described them in detail in TiDB Performance Tuning Guide (https://docs.pingcap.com/tidb/dev/performance-tuning-methods). Please refer to the tuning guide for more details.

2. The TiPerformance Channel on YouTube is a collection of short sessions presented by my teammates and me to share with you the performance tips we learned from real-world workloads. We have just released the first session: Find Performance Problems using the TiDB Performance Dashboard (https://www.youtube.com/watch?v=-hIkQE8YL-4), which is related to my session on P99 CONF. The second session will be released in October. Stay tuned!

Why attend your session in 7 words or less?

Learn how C# can be used for high perf systems.

What other session on the agenda are you most looking forward to and why?

Square Engineering’s “Fail Fast, Retry Soon” Performance Optimization Technique. Failure handling is easy, it’s obvious when something is wrong. Latency reduction is a lot harder, since there is no single culprit. I’m very interested in anything that can help in this regard.

For an even more fundamental education, make sure to read “The Goal” – one of the most useful books on Database Performance optimization, which does not have a single word about database performance.

Talk: cachegrand: A Take on High Performance Caching

Why attend your session in 7 words or less?
High performances and low latencies? Yes, please!

What other session on the agenda are you most looking forward to and why?

Removing Implicit Deadlocks on a Thread-Per-Core Architecture with 2-Phase Processing –  This is an approach that has been explored in cachegrand as in some rare conditions, depending on the user application, a user-level deadlock might happen and although cachegrand has an automatic abort system to deal with these cases it would impact the performances, implementing a 2 step processing algorithm to avoid it entirely is a huge win-win.

Using eBPF for High-Performance Networking in Cilium –  I use eBPF to debug and analyze the performances in cachegrand and it’s always interesting to see how other people use it, where they place hooks, which metrics they collect, etc.

Why User-Mode Threads Are Good for Performance – Fibers, or User-Mode threads, are a key component in cachegrand so seeing other usage of this approach is great. On top of it, I love the fact that Oracle is “resurrecting” the User-Mode threads in the JVM as I think they are really the key to provide amazing performances without using the “callback hell” approach where you have to pass nested callbacks of callbacks everywhere together with a nested status of everything.

Caching and Cache-Efficient Algorithms from MIT ( https://www.youtube.com/watch?v=xDKnMXtZKq8 )

Scott Meyers – Cpu Caches and Why You Care (https://www.youtube.com/watch?v=WDIkqP4JbkE)

Faster: A Concurrent Key-Value Store with In-Place Updates (https://www.microsoft.com/en-us/research/uploads/prod/2018/03/faster-sigmod18.pdf)

https://graphitemaster.github.io/fibers/ – It covers some concepts explained in cachegrand (the fibers) from “zero-to-hero” and it’s also relevant for the Oracle talk on the user-threads I referenced above.

 

Alex Hidalgo, Nobl9

Talk: Throw Away Your Nines

Why attend your session in 7 words or less?

You Might Be Doing It Wrong (Maybe).

What other session on the agenda are you most looking forward to and why?

Omar Elgabry’s “Square Engineering’s “Fail Fast, Retry Soon” Performance Optimization Technique.” We often spend too much time focused on making things more reliable on the first attempt when really we can often make things more reliable by failing fast and retrying.

Talk: Continuous Performance from Load Testing to SRE and Beyond

Why attend your session in 7 words or less?

Understand why your old performance is failing.

What other session on the agenda are you most looking forward to and why?

Omar Elgabry’s – Omar Elgabry’s – “Fail Fast, Retry Soon” Performance Optimization – I like the perspective of trial and error on performance issues. In the end, most of the time that is what we do to detect, diagnose and re-test that performance is right. The description of a real life situation makes this even more interesting.

P99 CONF Day 1: The Low-Latency Lowdown

Day 1 of P99 CONF kicked off with “misery metrics” and ended with a look at P99 latency reduction as a Sisyphean task. In between, engineers spoke of their many hard-fought performance battles and lessons learned. And thousands of engineers attending live had a great time digging into all this pain and suffering.
