I noticed that with 3.2.x kernels download speed from some internet resources became about half of speed that was with previous kernels (3.1 and older). I tested Fedora 15 kernels 2.6.41.10 = 3.1.10 and 2.6.42.3 = 3.2.3 (many times rebooted for testing with first and second kernels). See bug https://bugzilla.redhat.com/show_bug.cgi?id=789659
Hi, I tested last released 3.2.7 kernel (2.6.42.7-1.fc15.i686). 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 [off-list ref]
