Me too - it's not like I don't have anything else to do. :-)

I was just wondering why 3.10 was fine even with these settings and 3.12
wasn't. Here's the original report:

"I recently upgraded the Kernel from version 3.10 to latest stable
3.12.8, did the usual "make oldconfig" (resulting config attached).

But now I noticed some _really_ low network performance."
