Description Mike Fabian 2007-02-15 16:18:57 UTC

connection to krfb is *EXTREMELY* slow.

Comment 1 Mike Fabian 2007-02-15 16:24:49 UTC

My workstation “Magellan” runs Factory-x86_64.
I use a KDE session.

In the KDE control centre:

    → Internet & Network → Desktop Sharing

    Uninvited Connections
    [x] Allow uninvited connections
    [x] Announce service on the network
    [ ] Confirm uninvited connections before accepting
    [x] Allow uninvited connections to control the desktop

I can connect then, either remotely from another machine to magellan
or from magellan to herself.

Either way the connection works but it takes a *LONG* time until the
connection can be established correctly. Until then krdb consumes
100% CPU time. This can take several minutes.

This slowness problem does *not* occur on i386.

Another problem occurs on i386, see bug #245830, but not the slowness problem.

Comment 4 Mike Fabian 2007-03-21 11:42:55 UTC

This problem is still there.

The problem reported in bug #245830 suddenly disappeared when Stefan
updated Shannon to STABLE, but we can still reproduce the bug reported
here.

It is so slow that it is completely unusable.

Comment 6 Dirk Mueller 2007-08-02 15:31:08 UTC

can you try kde4-krfb instead?

Comment 7 Stephan Binner 2007-09-11 12:21:39 UTC

10.3 install kde4-krfb be default btw...
