I have a 2sec 70kb MP4, and a 10sec 227 kb MP4, and when iMovie combines them into one 12 sec file, it makes a 9.5mb file. WTF!
Anybody know of a more efficient way to merge two MP4s?

That happens because you're recompressing the video, and the configuration of the codec is notoriously wrong.

If it has to be MP4, use some good encoder which allows merging like StaxRip or meGui (both free, both GUI for multiple free encoders), and fiddle with the output bitrate. If it doesn't have to be MP4, MKVToolnix can merge movies into single MKV files.
However to avoid recompression both files have to use the same codec, and same frame size and rate. E.g. excerpts you've extracted from the same video. Otherwise you have to recompress at least one, but most often both. Even if you think codec/framesize/framerate match, if the streams are not 100% compatible they can't be merged. Same with audio
