Optimizing TCP/IP in Ubuntu 12.04/Gnome 3.6+
 

I was wanting to know if there is anything that I can use to optimize the TCP/IP settings in Ubuntu/Gnome. In Windows, specifically XP Home, I have been using TCP/IP Optimizer from Speedguide. It reconfigures the registry to optimize my computer for use on the Internet. Maybe it is just me but it seems as if when I am using XP I have a faster upload/download as opposed to Ubuntu/Gnome. I would prefer an app/util that uses GUI rather than having to go into the terminal to make any changes.

Seeing as Linux doesn't have a registry, you can't (in the way you're thinking).

First of all, can you try downloading the same thing using both OSes and time them carefully; preferably at least 3 times in each to get an average.
If you get a significant difference, please show the cmds and results.

...additionally if you're going to test best use a (command line?) tool that's available for multiple platforms like for example 'wget' and export contents of HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to a plain text file so you can compare settings with output of 'sysctl net.ipv4'. Additionally you should know the Linux kernel does a lot of auto-tuning so generally speaking it's best to not twist any knobs unless you know why. *This auto-tuning also means any performance tuning document, web log post or "HOWTO" explaining how to increase tcp_mem, tcp_rmem and tcp_wmem is probably old anyway and most of the time they won't tell you how to test changed settings in a meaningful way anyway.

Ok (I guess). I know that Ubuntu does have a registry as does Windows. I was just using my situation about XP as an example. Anyway, I will ... for now ... just leave it my set-up as is. Thanks.

There may be ways to reduce latency* but if your "speed" (or bandwidth) is different then I'd love to have an internet connection as fast as yours as I can max my 20Mb/s connection easily ;) without any additional playing.

Edit: If you're wanting something to make file downloading faster then something like axel might fit the bill but bear in mind that you can't download faster than your internet connection.

Might look up the old mtu settings for your isp type. Usually there is a ping test with option to see how large a window you can put on. Some IPv6 stuff out but usually it doesn't work on home systems.
