Are you using whitespace optimization during development? You should really be using :none which usually means compilation times in milliseconds.
Do you have any information on the kind of hardware the compile runs on? The numbers look horrible. Since you say heroku I imagine a VM in the Cloud which usually have very very terrible CPU performance. Do you have numbers from actual hardware? (eg. your dev machine) Other than that it is hard to say more without knowing the project. 259 files, 38k LOC seems like a lot though and is certainly the largest project I have heard of so far. At 15k LOC my project compiles+optimizes in about 20sec, so 421sec seems really high. Your concerns are valid. Tips for improvements are hard without knowing the project, it may just be the hardware but it probably is more than that. Shameless plug: You could also try shadow-build [1] which can be faster than other tools but usually not by _that_ much. I'd be interested on what the output of shadow-build looks like though since it provides much more detail.
