Why Is My AI Coding Agent Slow? Most of the Wait Never Leaves Your Machine (2026)

A slow agent turn is a stack: context gathering across thousands of file reads, subprocess spawns, language servers, MCP round-trips, TLS setup and inference. Only the last is the model. Here is how to measure where a turn actually goes on Linux in 2026, with claudefeed and exectop.

How Do I Find an N+1 Query From API Traffic? (2026)

An N+1 does not fail, it just makes two hundred calls where one would do. Your ORM logs each query as a success and your APM shows a slow endpoint without saying why. Here is how to find N+1 queries and chatty API calls on Linux by counting what actually crossed the wire.
