does anyone know why X windows seems to be so slow? I think it should really fly if you are using a local X server in windows. At least that is my experience with running a Linux distribution under VMWare. My machine isn't that slow and there is barely any CPU usage when the X server is doing it's job (between 10-15%) so I don't know what is going on.
I am using an Athlon XP 3200+ and X is barely usable. At least compared to running remote applications on my other 450MhZ machine.
Any ideas? Could it be a TAP driver bandwidth problem?
I suspect the problem may be with the Win-TAP network interface. I did a simple test by using plink to connect to the chargen port on the colinux machine and re-directing the output to nul i.e.:
plink -raw -P 19 colinux > nul
When I watch the Win-TAP network connection I see a maximum throughput of 20 megabits.
I've seen the same performance using scp and ftp.
Than using iperf, i've found the performance in about 1.33mbps.
Makes me wonder whether it would be possible to use anything else (instead of TAP). Hmmm.
I noticed my tap-win32 network connection displays
"Connected at 10Mbs". Is that a default setting. Can it be changed to 100Mbs or 1000Mbs ?
Yes, i found this "Connected at 10Mbs" strange ...
I have a pIII 800mhz.
Next weeks i ill buy a new portable. My question is: someone is using kde in colinux on a p4 2.8 or 3ghz cpu ?
What you can say about colinux+xwindow perfomance ?
I tried to use it on a P4 3GHz. It's very slow. I use fluxbox now.
It's obvious, that bridget networking would be better. but i'm not sure, if that is a secure way :-)
the other issue with bridged network (i didn't run any bench till yet) is that i can connect to al hosts but not the local machine. so we all need an "loopback" device. there could be much more performance to win.
A slow network connection would not adiquately explain slow X11. If your X11 settings are properly configured you can get acceptable X11 connections over a modem...
I just benchmarked to see what kind of throughput I get from my colinux machine, and found the speed is about 24MBs with a ping time of 6ms. This certainly is not slow by network standards. But then again, X11 does not seem much slower than booting Linux natively.
