A 2HP router is on the low side for 3M/min feed speeds, if you're cutting 19mm panels in a single pass. I'd say use no less than a Porter Cable 7518. Tooling plays a big part in this as well. On our commercial machine, with chipbreaker spiral tooling I can cut 19mm plywood at 10M/min, but with insert tooling I slow down to 3-4M/min, or risk breaking the tool. This is with a 10HP spindle, btw.
You might also want to look at higher lead ballscrews, 10-20mm instead of the 5mm you mentioned. This will reduce whipping, and keep the motors spinning slower where they have more torque.
