We’ve updated our article on OPcache configuration with new insights from our recent video.

It now covers the three configuration options responsible for most performance gains, plus additional OPcache details and tuning tips.

I'm excited to share that my new book, Performance Engineering in Practice, is now available through Manning's Early Access Program! 🎉

For 25 years I've seen the same pattern: performance problems surface after users complain, teams panic, patch, and repeat. I call it the Performance Decay Cycle.

This book is the practical guide to breaking that cycle. First 5 chapters available now with 50% off at launch 🚀

Back in 2017, Yao Yue embarked on an exciting journey, joining a brand new team at #Twitter - Performance Engineering, aka the IOP Team.

This team made waves over the next 5 years: saving Twitter over $100M creating some of the largest data processing jobs owned by infra, driving multiple company-wide initiatives, and releasing multiple open source projects and publications.

Listen to this #InfoQ talk as she reflects on this experience, sharing invaluable insights on effective #PerformanceEngineering: https://bit.ly/49JSLmy

Spoiler alert: it's all about platform building!

Great post from @nelhage on profilers, how memes say you should use them, and how expert performance engineers actually use them.
