I'd be REALLY surprised if the impact of the extra indirection were more than a couple of milliseconds per file, on Windows. So if we build 2000 files, the total cost would be 2-4 seconds of CPU time. Remember to divide that by the number of parallel compilation jobs to get the wallclock time. So, if the total cost is more than 1 second in the full build of qtbase, I'd be surprised. Besides, that's what SSDs and good filesystem engines are for. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
