If you want to get all the needed DBs loaded and caches built quickly, 
there are a couple options.

One is to set semantic-idle-scheduler-work-idle-time from 60 seconds to 
5 seconds, basically, something that will get all that stuff gathered up 
early in some idle moment that isn't a minute long.

If you'd like it to do that loading when you load a file, in a mode 
hook, or something like that, you can run 
semantic-idle-work-for-one-buffer, or look at that functions contents 
and pull out the bits you want, which I believe would be these two calls:

(semanticdb-find-translate-path buffer nil)
(semanticdb-typecache-refresh-for-buffer buffer)
