I am affected by this bug as well. I run BOINC and Hardy on two computers and occasionally transfer files between them. Network performance degraded quite badly. Was getting as low as 300KB/s on Ethernet (10/100).
I did testing using:
time md5sum /dev/urandom & pid=$! ; sleep 10 ; killall md5sum
time nice md5sum /dev/urandom & pid=$! ; sleep 10 ; killall md5sum
Results:
bryan@homer:~$ time md5sum /dev/urandom & pid=$! ; sleep 10 ; killall md5sum
[1] 7822
bryan@homer:~$ bash: line 1: 7823 Terminated md5sum /dev/urandom
real 0m10.116s
user 0m0.112s
sys 0m8.589s
[1]+ Exit 143 time md5sum /dev/urandom
bryan@homer:~$ time nice md5sum /dev/urandom & pid=$! ; sleep 10 ; killall md5sum
[1] 7857
bryan@homer:~$ bash: line 3: 7858 Terminated nice md5sum /dev/urandom
