Speed problems in 3.2.7 the same as in 3.2.6. I also have Fedora Rawhide installed in virtual machine (e1000 driver used there) running on host with 3.1.10 kernel. And I noticed that after one of 3.3 rc's (or even rc's of 3.2) kernel updates download speed of updates from dl.fedoraproject.org in VM became extremely slow - about 160 kilobytes/sec instead of 1,2 megabytes/sec as it was before. But recently (somewhere between 3.3 rc3 and rc4) speed became again as it should 1,2 MB/s. Don't know is this problem related with speed in 3.2.x kernels and it is hard to debug this now. -- Alexey Kurov <nucleo@...oraproject.org> -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
