Indeed it's only a workaround and it's not bulet-proof. As far as I'm concerned, I now completly disable windows scaling because this morning I experienced some issues. Moreover, bye only changing the scale factor, you do *not* ensure that you can actually communicate with every host. There might still be some unreachable hosts, even if you're not aware of them. > So I get much better network performance disabling scaling than with the > tcp_rmem setting.

My main point was > that Arch should provide a workaround by default. For sure. But if it's done, we should let the user know about it. I'm affraid of that Arch include a lot of workaround I'm not even aware of. I'm an ex-Slacker and that's not something I appreciate much.
