Done that, been there. Always getting responses pointing at hardware, OS, disk-space etc. Sorry guys, it really has nothing to do with that, its QB that is simply slow, period.

When posting something like building of 100 assemblies, rest assured, you'll be on the computer for over an hour, half of that time you are waiting for the tee-tee confirmation tone.

Its simply that way. What speeds up the process is navigating away from the build-screen instead of waiting, like going to Chrome or another (unrelated) file.

The next thing you need to know is that if you click "build and new", you are faster than "build and close".
