The constgrep tool could probably be a bit faster. I'm not sure what's making it so slow at the moment. It shouldn't take ~2 seconds to look up a value.

Honestly it might just be fastest to pass e.g. pwnlib/constants/linux/i386.py to grep directly and do some post-processing (or just invoke the lines).
