Is the slow
behavior only when using Gazebo and rviz? What kind of graphics card do you
have, and are the drivers properly installed?

Hello everybody,
When I run Gazebo and rviz on my Athlon 64 3500 (one
core) 5 year old machine running Kubuntu Lucid 32-bit,
the cturtle looks more like a c-snail. With CPU at 100% all
the time, I see updates in rviz about every 5 seconds.
So it takes about 30 minutes to get across a hall of WG.
Which is not that much fun, and now I'm looking at the
ways to improve this situation:
a) Upgrade processor to dual-core AMD Athlon 64 X2 (dual core) and
install 64-bit Linux.
b) Run Gazebo on another machine
c) Get a new AMD Phenom II X6 (six cores) machine
d) Try to mess with performance of Gazebo as outlined by John
here: http://ros-users.122217.n3.nabble.com/cpu-usage-of-Gazebo-td911241.html#a913849
I searched this list for AMD/Athlon and did not find much.
I'm guessing that's because WG uses Intel Quad Core i7 Xeon
processors.
What would you guys recommend?
I understand it's hard to recommend PC hardware, but I'm
asking here to get a feel of what would be a good solution that will get
me going with ROS for another couple of years.
So far my impression is ROS is highly multi-process system and
probably going to get even more so in the near future. Thus I was looking for a
CPU with more cores. Am I going in the right direction?
Thank you for your time,
Alex
