Anyone else experiencing an increase in MacOs performance degradation when subagents are used in a claude code session? It started for me ~2 weeks ago I think. It’s been hard to remember exactly when it kicked off because the perf issues aren’t show stoppers, they’re just annoyances. When running subagents, my mac seriously struggles to open windows. Once the window is opened and initialized, the it runs fine. But there’s some bottleneck around window opening when I have subagents running. And to be clear, it can be from just one subagent, not swarms. Anyone else? or is this maybe just local to my machine? submitted by /u/OkLettuce338
