Back to newsletter 290 contents

What a year! In October I covered how GenAI+LLM is reducing the expertise needed to analyse performance issues, September saw me cover how the Elastic donated eBPF continuous profiling will become ubiquitous, and when combined with my May newsletter explaining how profiling and tracing are now integrated, suggests the future is much deeper observability for a quite low overhead cost!

We finally saw the Foreign Function and Memory API released after 10 years of development, I covered how you need to understand a different style of GC tuning, a different style of IO implementation, a different style of startup with CRaC, and my guest contributor Ingo Kegel explained how thread-local handshakes can give you near-zero overhead for full sampling without async.

There was so much more (OpenTelemetry, Eventual consistency, K8s related tuning, all the performance changes from two JDK releases, serverless ...). All the newsletters are available!. Now on to all the usual newsletter list of links, tips, tools, talks and news, and as usual I've extracted all the tips into this month's tips page
