Hi Michael,
I'm trying out x2go in thin client mode on more recent hardware (ZOTAC
ZBOX, AMD E-350, 2 GB RAM).
I experience both bad performance and high CPU load the client side,
even worse than on my legacy Intel P III 1 GHz systems some time ago.
Notable the x2goclient process consumes about 30% CPU time (one of tow
cores) whenever a session is active - even a simple terminal (single
application -> terminal) waiting for input.
Which options are recommended for local (1 GBit LAN) usage?
you should check if your terminal is using the nvidia xorg driver or the
xorg Nouveau driver or the basic vga emulation on cpu. I guess your
terminal is using the cpu based vga rendering.
my ZBOX isn't Atom/ION-based but AMD based. Therefore the radeon driver
seems to be used. The drivers is loaded and X11 refuses to start when
the radeon firmware for the framebuffer driver is missing.
sorry for the mislead answer. I bought a few zotac recently and all
where ion based. We are using in house debian-live for booting x2go
terminals (http://live.debian.net/), and I had issues with outdated
nvidia driver in debian and all the rendering was done on plain vesa
driver, which needed a whole lot of CPU.
How can I check whether "cpu based vga" isn't active?
Please note: the CPU time is consumed by the x2goclient process not by
the Xorg process.
I'm currently running on a x2goclient running on a zotac (Intel Atom
D510, nvidia GT218 ION), and doing standard work (no intensive graphic)
takes between 5-10% cpu on the client side.
cheers,
Denis
Michael
