How to speed up g++ compile time (when using a lot of templates)

Question

This question is perhaps somehow odd, but how can I speed up g++ compile time? My C++ code heavily uses boost and templates. I already moved as much as possible out of the h

Here's what I've done to speed up builds under a very similar scenario that you describe (boost, templates, gcc)

• build on local disk instead of a network file system like NFS
• upgrade to a newer version of gcc
• investigate distcc
• faster build systems, especially more RAM
