beachycove, it does keep pipelines more full and that probably explains some of it because the CPU can do more work a larger percentage of the time. But I sure couldn't go back to 10.0.1.
CT, some of it. This will get submitted back to them, yes. The 10.4 specific stuff, I don't bother; they probably don't want it anyway. But the cross-POWER stuff could be valuable for Linux and AIX, so I send those, as well as cross-platform bugs such as the ones in layout that assumed a one-byte boolean (PPC natively uses four-byte booleans because it's faster).
