disabling ipv6 to improve network speed

[Gorilla]

is it worth disabling ipv6 on all my machines to improve my network speed.

[Mibz]

No.
And if you run Windows 7 you're likely to break shit if you disable it.

if you want to improve network file browsing speeds disable tcp acks, in win7 they are set to 200ms it's retarded, otherwise if you have gigabit and are copying large files between 2 computers and are getting 50-60MB/s then speed is fine as you are maxing the drives out, but if it's slow changing folders or deleting large amounts of files over network turn off tcp acks

Just be aware that with IPv6 you could be compromised with a rogue IPv6 DHCP server as well as have a DoS attack on your computer through RA flood attacks. I've turned off IPv6 on my Windows 7 computer before without any negative impact but I also didn't see any positive results either.

Bart, do you have a link referencing this? It just seems odd to do to disable your computer from sending TCP acknowledgements. Wouldn't this cause other issues breaking TCP sessions and limiting TCP windowing?

If you're worried about network speed you should focus on increasing link speed first.

here is how you do it: http://windows7themes.net/how-to-improve-latency-in-wow-in-windows-7.html

my samba shares were slow ass, i had to wait up to a full second when changing dirs or trying to rename files on those shares, now with the fix it flies as if the files were on the local disk

file copying was still ok from the start, once it actually started going it was going full speed
