[ros-users] c-snail

[Alex Barvo]

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:

 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
