Hi Guys,

After getting some encouraging words about loopback here, I did some testing to see if there was any advantage in using loopback for X. I was totally let down speed wise. I don't know if I did something wrong. Here is a rundown of what I tried:

I created a microsoft loopback adapter called "MS-Loopback". Assigned it IP,, gw= Its listed as 10Mbps. (why??)

Then I installed winpcap 3.1. I used eth0=pcap-bridged,"MS-Looback"
 and eth1=tuntap,"TAP-Win32". "TAP-Win32" is bridged with
 "Internet" adaper which is connected to my router.

I assigned IP of, gw= to eth0 in colinux. I assigned IP of, gw= to eth0. And proceeded to test speeds:

1. Using address, scp from Windows to colinux goes at the speed of 14Mbytes per sec.
2. scp from colinux to Windows using goes at 2Mbytes per sec. If invoke scp from colinux which copies from Windows to colinux, the rate becomes 5Mbytes per sec.
3. X is sloppy when I query X is faster when I query This is clearly visible when I switch workspaces in gnome.

So, why is it that the X connection thru the physical router is faster than the MS loopback connection?

Why from windows to colinux the speed is faster but its 1/7th the other way? Why are loopback adapters shown as 10Mbps? Is there a way to change that?

Did I do something wrong?

Thanks for your time,
PS: I forgot to mention that I am using colinux-060309 Henry's snapshot.
