This is a pretty tough question. First of all, I would get your boss to qualify and quantify the statement. Because "accelerate your lab" sounds very much like an empty buzzword, and you deserve a better explanation if they want results. Are you moving too slowly, not getting enough samples done? Quantify, that is you, count how many you do, and keep a running track from day to day. I keep a small notepad in my shirt pocket, although you kids probably have an app for that. If they want better work, make them describe what was lacking, and then you can see how to improve.
But definitely tell them, to qualify and quantify their buzzwords.
