[X2Go-User] Suspending sessions causes performance slowing down

[Ulrich Sibiller]

Hello,

the sleep is thought to reduce load when a session is not in use. If that
is undesired you can set it to 0 as you already found out. In that case
X2go or rather nx) does not need to transfer data from the server to the
client and therefore is faster. I don't really see how this could be
smoothed with the current software.

_Maybe_ you can improve the situation by setting sleep to 0 and use the
superrenicer feature of x2goserver. See /etc/x2go/x2goserver.conf. I have
no experience with this, maybe someone else can add more information here.

Uli
