[X2Go-User] Suspending sessions causes performance slowing down

[Ulrich Sibiller]

One more thing: Maybe using -irlimit could help here, too:

-irlimit <kB/s>. This will limit the amount of data that
is used to update drawables on the real display. It can only be passed
via command line. To play with it add it to
/etc/x2go/x2goagent.options.
