What techniques can be used to speed up C++ compilation times?
This question came up in some comments on this question: http://stackoverflow.com/questions/372862/c-programming-style
And I'm interested to hear what ideas there are.
I've seen this related...

Use Parallelism Many compilers / IDEs support/cores will all make a difference in compilation speed.
Advantage of caching techniques to speed things up.

In fact, some (e.g.

I bought a used speed sensor from BH a few months ago, it was seized in the damaged bracket, but I managed to extricate it an fit it on my car. Sadly still no speedo, I assumed it was the wiring/speedo itself, however I bought a cheap Chinese USB Oscilloscope...

I presume.
I think that with the speed sensor it needs to be within a mm or so of the sensor ring.

You can use to write to RAID-5.
Fragmented? Fragmented reads can be an order of magnitude slower than contiguous reads .

I'm currently working through an assignment that deals with Big-O and running times. I have this one question presented to me that seems to be very easy, but I'm not sure if I'm doing it correctly. The rest of the problems have been quite difficult, and...

But with Big O you could not deduce an exact running time even given the speed of each operation.
N^3 data is called "running time", but that's because the model used for speed evaluations assumes.

Perceptible to end-users, but it should be there.
You can use tune2fs to query and/or set the dir_index feature for ext3.
