Nick speaks wisely. Your problem is underextrusion but there is a third cause he didn't consider:
Is your infill speed faster than your print speed? If so then you can leave the print speed alone - you only have to slow down the infill speed (or raise temperature). A part like this appears to have no stringing issues (no times when the head jumps a gap) so I would print it at 240C. At 240C you can print much faster than at 190 to 210C.

Yeah, i've struggled with this from time to time. It has a lot to do with the viscosity of filament when melted. It also has to do with a nonlinear relationship between extrusion force and amount of material extruded. I would try raising the temp 10°and lowering your infill speed 20mm/s. If that solves the problem, you can probably try to find a middleground somewhere faster and cooler.
Generally speaking, though, it looks like your print is underextruding regardless of the infill qualtiy. I would try raising the temp and increasing your flow rate until your solid sections are printing with good density, and then tackle the infill problem. You may end up solving both at once.
