Dynatrace supports SnapStart for Lambda as an AWS launch partner

Dynatrace

NOVEMBER 28, 2022

Today, application modernization efforts are centered on application programming interfaces and microservices that are sensitive to startup latency. For AWS Lambda, the largest contributor to startup latency is the time spent initializing an execution environment, which includes loading function code and initializing dependencies.

AUGUST 18, 2019

It was created by Alastair Robertson, a talented UK-based developer who has previously won various coding competitions. bpftrace uses BPF (Berkeley Packet Filter), an in-kernel execution engine that processes a virtual instruction set. The probe is BEGIN , a special probe that runs at the beginning of the program (like awk).

OSes usually show you virtual memory and resident memory, shown as the "VIRT" and "RES" columns in top. Short durations can be useful for understanding how well a WSS will fit into the CPU caches (L1/L2/L3, TLB L1/L2, etc). That's the working set size. It is used for capacity planning and scalability analysis. Consider these overheads.
