Investigation of a Workbench UI Latency Issue

The Netflix TechBlog

To investigate this issue, we needed a quantitative analysis of the slowness. har file recording all communications from the browser and loaded it into a Notebook for analysis. Using this approach, we observed latencies ranging from 1 to 10 seconds, averaging 7.4 j”) for 15 seconds while running the user’s notebook.

Noisy Neighbor Detection with eBPF

The Netflix TechBlog

The first step is determining whether the problem originates from the application or the underlying infrastructure. Traditional performance analysis tools such as perf can introduce significant overhead, risking further performance degradation. We then calculate the run queue latency by simply subtracting the timestamps.

OpenTelemetry 101: A nontechnical guide for IT leaders and enthusiasts

Dynatrace

Text-based records of events and activities generated by applications and infrastructure components. Traces are used for performance analysis, latency optimization, and root cause analysis. You’ll also need to configure exporters, which determine where OpenTelemetry will send the data it collects for analysis.

Dynatrace supports SnapStart for Lambda as an AWS launch partner

Dynatrace

The new Amazon capability enables customers to improve the startup latency of their functions from several seconds to as low as sub-second (up to 10 times faster) at P99 (the 99th latency percentile). This can cause latency outliers and may lead to a poor end-user experience for latency-sensitive applications.
