[Bug] Claude CLI experiencing excessive response latency

Bug Description
Claude CLI is experiencing severe lag / response delays Hi Anthropic Team, I’ve been using the Claude CLI, but recently it has become incredibly slow. The time between sending a prompt and receiving the first token (or full response) is taking much longer than usual. Is there a known server issue or a recent update causing this performance drop? Thanks!
