Hey Y'all,
Were there any responses to this that I may have missed?
While I have a very slow & crappy internet provider, I'd like to try
this to see if I can get even 10Kbps (yes, 10 K!) more. I don't have any
60-* in my sysctl.d directory, only 10-*. Do I just add another 10-, or
should I put a 60- in here or somewhere else?

It is more kernel tweaks, like:

Ok, I've done this, and it seems to be about 5% faster.
Anyone have some additional suggestions?
