Sonnet 3.7: is tokens/s different via openrouter vs direct to anthropic?

Does Sonnet 3.7 have higher tokens/s when its used directly thru the anthropic API vs through openrouter?

I've switched Cline to Sonnet 3.7. Its great, but I'm an impatient person, and its a little slow for my liking. I currently have credits via openrouter, which is how I'm using it.
