| Is there any point to this other than the obvious "because I can", did you notice any performance gains over a gcc compiled kernel? |

The bfs 232 patchset? do you notice any improvements over say... 211?
I tried it when it was 211 and while it did seem ok, it would cause lockups with 3D games

| I definitely notice a difference when compiling with the BFS patch, I am in the process of running some benches comparing the icc kernel to vanilla 2.6.31.1 and vanilla patched with the bfs 232 patch and I'll post the results, hopfully with favorable reults |

How did you manage to compile linux with a c++ compiler?

C++ is a superset of C, with a few exceptions. I doubt there's a C++ compiler anywhere that doesn't do both. |

| there are significant gains with the BFS patch with or without compiling with icc.. although the 3d tests show about a 5% gain with icc vs gcc... |

| Just for info: BFS is now at version 0.240. This version includes a very important bug fix that corrects issues with stalled processes (like 3D apps freezing and being unable to kill them.) |
