Leveraging eBPF for Analysing Performance of the Linux SMB Client (sambaXP 2025)
Talk from Meetakshi Setiya (Microsoft) at sambaXP 2025.
Abstract:
Linux users often ask: Why is my application slow? How can I improve performance? Why did it crash?
This presentation introduces new diagnostic tools from the Azure Files team for troubleshooting Linux SMB client issues. After a brief overview of existing tools for latency and diagnostics, the focus will shift to new eBPF-based (BPF CO-RE) scripts. A technical overview and live demonstration will show how these tools collect and analyze key data in common failure scenarios.
Attendees will also get a glimpse of the upcoming Always-On Diagnostics project, aimed at enhancing debugging on the Linux SMB client. Feedback is welcome to refine these tools and improve Linux SMB performance analysis.
