It was set to "Programs". Changing it to "Background services" didn't make
a difference.
TCPOptimizer can adjust 2 registry entries that I think are related to that
Windows Setting:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Multimedia\SystemProfile]
"NetworkThrottlingIndex"=dword:0000000a
"SystemResponsiveness"=dword:00000014
The first rate-limits IP packets; the second reserves a percent (0-100)
of CPU scheduling for background tasks. Changing either of those values made
no difference. I think the CPU scheduling reservation only applies when
there's CPU contention (not on an idle system) so I wouldn't expect it to make
a difference when CPU/core usage is low.
