It'd be interesting to see some compilation times in the (other than that) great reviews performed by the Phoronix team - there should be a specific couple of GCC-Version, and, say, a Linux Kernel snapshot, which is run with its default config via "cd /usr/src/linux/ && make -j$NUMBEROFTHREAD" (where $NUMBEROFTHREADS could be the same for all test (e. g. 4), or a fixed number per core, to make the banchmarks somewhat future-proof). Then again, there could be a second benchmark, compiling the same Kernel snapshot at the time with the most recently released GCC.

This on one hand would give users a clue about what to buy if they strive to cut compilation times, and on the other hand give insights about the progress of GCC development.

What do you think?
