Description Michael Young 2007-01-31 11:53:44 EST
We have recently updated some servers which provide remote gdm login sessions
using X to a gnome desktop from FC3 to FC5, and have noticed them running slowly
at times. The reason seems that when there are enough sessions, we are hitting
the bandwidth limit on one of our network links, and this in turn seems to be a
consequence of the network traffic involved being 3 or 4 times what it used to
be compared to FC3. FC6 is similarly bloated. I am not entirely sure which
package is causing this, but it affects most applications including the gdm
login, so I suspect it is some low level library like gtk2.

We decided in the end that the problem was that 16-bit colour was taking up much
more bandwidth than 24-bit colour in the newer versions of Fedora, but in the
end we moved to a vnc based solution that was more efficient that either of them.
