I just checked if Debian had clang/LLVM, and interestingly:

It included a link with actual compile times:

See the full report for explanation, but the following looks good.

These are the average compile times for compiling a file in a set of 100 randomly selected files: (time values in seconds) gcc 4.4 gcc 4.6 gcc 4.7 clang 3.0 clang 3.1 -fs-o -O0 0.450 0.458 0.501 0.449 0.439 -O0 0.624 0.631 0.684 0.504 0.494 -O0 -g 0.722 0.727 0.781 0.661 0.653 -O2 0.811 0.803 0.874 0.603 0.597 -O2 -g 0.916 0.979 1.06 0.809 0.809 These are the average compile times for compiling a file in the set of the 10 files that are slowest (as when compiled with gcc 4.4 using -O2) to compile: gcc 4.4 gcc 4.6 gcc 4.7 clang 3.0 clang 3.1 -fs-o -O0 2.18 1.70 1.86 1.70 1.66 -O0 5.87 5.33 5.71 2.90 2.85 -O0 -g 6.71 6.19 6.61 4.00 4.08 -O2 11.9 10.8 12.0 6.72 6.80 -O2 -g 13.2 13.6 15.1 9.57 9.78
I usually compile with '-O2' which looks very good.

[marto]: lazyweb Q: so an IE window apparently opened via JS with toolbars=no, all other IE instances closed. Click a URL in an email or whatever, and it doesn't open a new window or tab.
[marto]: does JS lock down windows created via to prevent this?
