The two screencasts below are a preview of what’s coming next week, when I formally introduce the latest xtop and xcapture v3 to the world. On next Tuesday, 19th August at 1pm EDT, I’ll upload the latest (beta) open source code to 0x.tools repo and run a 1-hour “hacking session” style webinar. It’s gonna be all demos of how I use these tools for my troubleshooting work.

In this post I will introduce a much more efficient method for accounting block I/O latencies with eBPF on Linux. In my stress test, the “new biolatency” accounting method had 59x lower CPU and probe latency overhead compared to the current biolatency approach. So I couldn’t help it and ended up putting 21 NVMe SSDs into one of my homelab servers. 8 of them are PCIe5 and the remaining 13 are PCIe4. - Linux, Oracle, SQL performance tuning and troubleshooting - consulting & training.| tanelpoder.com
