Did workers get slower?

I've had a worker running for years just to test the speed of Cloudflare services. Today, I tested the new KV speed improvements, and they showed significant progress—down to 3-5ms from around 25ms+ after a cold start. However, the worker seems to have slowed down overall. I haven't changed the code in years and have tested it multiple times. While 135ms for a simple response (waiting for the server) isn't too bad, it feels slower than before. I recall response times being around 50-60ms previously. Have there been any recent changes that could explain this?
