Too high RPM is generally defined as above the 'redline' for a particular
engine. That is to say, the max RPM that you are assured the parts in your
engine will hold up to. I seriously doubt any Honda 4 banger has a redline
below 5000 RPM.

For best fuel mileage you should rpobably shift around 2,000 RPM (with a 4
banger anyway), for best performance you should probably shift at or
somewhat below redline. Where you shift when desiring max performance
depends on where your engine's power peaks. If it runs out of breath at 6000
RPM then shift there, but if it makes good power all the way up to a 7500
RPM redline shift at 7500 RPM.
