Fastest RDP client on linux

Question

I currently use KRDC on CentOS, but mouse pointer is a little slow and I'm sure that this is not caused by my internet line speed, because the windows RDP client works and everything is fine. Which RDP client is the fastest on CentOS (or any other Linux OS)?

Answer 1

KRCD and I suspect all other Linux RDC clients use rdesktop under the hood.

I'd encourage you to play with the settings of rdesktop, I myself have used it without any speed issues. It's very possible that your windows RDP connection uses different options, espescially the -x paramter to rdesktop:

Changes default bandwidth performance behaviour for RDP5. By default only
theming is enabled, and all other options are disabled (corresponding
to modem (56 Kbps)). Setting experience to b[roadband] enables menu
animations and full window dragging. Setting experience to l[an] will
also enable the desktop wallpaper. Setting experience to m[odem]
disables all (including themes). Experience can also be a hexidecimal
number containing the flags.

Answer 2

I cannot comment on performance/speed of various RDP clients. However I recently came across the FreeRDP project that describes itself as follows

FreeRDP is a fork of the rdesktop project that intends to rapidly start moving forward and implement features that rdesktop lacks the most.

I have not use KRDC but I have used both rdesktop and xfreerdp clients from the commandline on Ubuntu 10.10 and they are both usable. xfreerdp accepts the same -x option as @gnud mentions and that option is likely to make the biggest difference in performance.

Answer 3

I've taken to using Remmina lately. I use it mostly because it manages a list of hosts and their settings quite nicely, and can set up an SSH tunnel automatically. It does VNC too.

I haven't had performance problems with RDP in general though, and haven't used KRDC, so I couldn't say it would necessarily be any different from that point of view.

I don't know if Remmina is available in CentOS's repository.

Answer 4

OK, we find the problem :)

It seems that rdp client have some trouble with win7, so we try KRDC on others OS (centos, ubuntu and XP) and it work great...

Conclusion: The problem is not in RDP Client, but on the system on which we want to connect...

Thanks for your answers!
