I presented my talk on "Deterministic Simulation Testing" yesterday. If you missed the stream, here's a recording: youtube.com/live/29Vz5wkoU… Thanks Juho Vepsäläinen and Future Frontend for co-organizing and the awesome audience for first Systems from HEL!

Uncached buffered IO is back, after a 5 year hiatus. Simpler and cleaner now. Up to 65-75% improvement, at half the CPU usage on my system. And none of the nonsense of the unpredictability of the page cache. See commit 1 and 3 for read/write perf data. git.kernel.dk/cgit/linux/log…

I've been catching up on CS papers from the past six months, and wow...DBLP is so awesome. It makes it so easy to find all of the papers in a single place. Great example from Networked Systems Design and Implementation (NSDI): dblp.org/db/conf/nsdi/n…

Practical Benchmarking: How To Detect Performance Changes in Noisy Results bit.ly/4iog2z8 by Matt Fleming

we are looking for a p99 engineer to work on infra/autoscaling/k8s tooling for the 10s of clusters (soon 100s) we run across all 3 clouds. dm me

Full report for yesterday’s Google outage - not feature flagging a new code path - null pointer crashing a binary when reading empty fields from Spanner - remediation causing a thundering herd as there was no exponential backoff - which required manual throttling to recover from

Me and ⁦Jesper D. Brouer⁩ wrote a blog post on the kernel’s BPF LPM trie implementation and cover some of the performance gotchas with the current code. blog.cloudflare.com/a-deep-dive-in…

Performance Hints Over the years, my colleague Sanjay Ghemawat and I have done a fair bit of diving into performance tuning of various pieces of code. We wrote an internal Performance Hints document a couple of years ago as a way of identifying some general principles and we've
