Bug#487635: Performance degradation over remote ssh X11 forwarded display
Package: libx11-6
Version: 2:1.1.4-2
Severity: important
Since upgrading libx11-6 in lenny from 1.0.3 to 1.1.4 we're seeing
severe performance degradation when using applications over a remote
ssh X11 forwarding tunnel. The applications we've seen this happen to
are: netbeans 6.0, icedove, firefox 3.0 . When used on a local X11
display these applications perform normally, but when used remotely
they become extremely sluggish making them practically unusable. I do
not observe any excessive cpu or network usage though. Reverting the
package version back to 1.0.3 (or using LD_PRELOAD to force using the
1.0.3 version of libX11.so.6.2.0) is usable as a temporary workaround.
