Mercedes have the highest downforce and therefore most drag of any team, so of course, their straight-line speed will be compromised.
Is that so, or it's just everyone recognizes it but also thinks the PU difference plays a bigger part, hence all the talk about the engine power?
Pat Symonds, in his mid-year report on Autosport explains this well. Not sure how many people have autosport premium, not exactly worth, but once in a while there are good articles. Here is what he say.

A Small excerpt from the article.
But what of the challengers? Ferrari's pre-season form flattered to deceive. Its straightline speed was widely put down to an improved power unit, which perhaps even exceeded the performance of the long-dominant Mercedes engine.
In reality, acceleration data showed the two engines to be very evenly matched and the prodigious terminal speed of the Ferrari had more to do with lower drag than higher power.
The 5km/h difference seen in typical terminal speeds would have required a further 50bhp on a car with equal drag, but if we assume the power units to be equal it could also be achieved with around five points less drag.
Now, if we assume the two cars have equal aerodynamic efficiency then the five points of lower drag might equate to around 18 points less downforce, which in turn would show as a lap time deficit of around five or six tenths which, Bahrain excepted, is about what we are seeing.
