Some "tweak" software says enable the following have positive effect on networking
1. path MTU disocvery
2.large TCP windows support
3.sackopts
Is it true, or mostly placebo or outdated features?

I can't comment on newer versions but for XP they are very real. Before tweaking speeds were limited to about 400kb/s.
Here I found some old config that I had applied, which made speeds upto 3.5mb/s possible that my ISP provided:
Code:Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] "GlobalMaxTcpWindowSize"=dword:000faf00 "TcpWindowSize"=dword:000faf00 "Tcp1323Opts"=dword:00000001 "DefaultTTL"=dword:00000040 "EnablePMTUDiscovery"=dword:00000001 "SackOpts"=dword:00000001 "TcpMaxDupAcks"=dword:00000002
146000 (default)
256960 (>3.5Mbps)
513920 (>11Mbps)
1027840 (>21Mbps) hex: 000faf00
2055680 (>42Mbps)
4111360 (>85Mbps)
Windows network "tweaks", are they real?
