kern/152828: [em] poor performance on 8.1, 8.2-PRE

[Steven Hartland]

It stalls on just a basic file scp. Our current test is to scp the freebsd
iso to the machine. It won't always do it but it does "seem" like once its had
one stall its very much more prone to repeat stalls.

Here are some examples of what we see:-

FreeBSD-8.2-RELEASE-amd64-disc1.iso        41%  284MB   0.3KB/s - stalled -Read from remote host test01: Operation timed out
lost connection


world-2011-05-15-09-53-16.tar.gz           100%   67MB   3.4MB/s   00:20    
world-2011-05-30-07-35-37.tar.gz           100%   68MB   5.7MB/s   00:12    
world-2011-05-05-23-51-00.tar.gz           100%   50MB   3.6MB/s   00:14    
world-2011-06-06-14-20-09.tar.gz           100%   81MB   3.7MB/s   00:22    
world-2011-06-15-09-10-42.tar.gz            44%   61MB  41.5KB/s - stalled -^world-2011-06-15-09-10-42.tar.gz
