Application Performance:
When setting up a multi-user environment, testing of your applications in a typical usage model
should be conducted to determine that the configured PC's resources (CPU and memory) are
sufficient to meet performance expectations. Any dual core system from 2008 and beyond should
more than meet the vast majority of application performance needs for most educational or
business users. The following data show how well 10 users can run on a standard PC available in
the market today.
If your testing indicates that a system's dual core processor does not meet your performance
needs, then the option is to improve the resources in the host PC by going to a faster processor or
using one with more processing cores.
Internet Performance:
There is really no difference between running 10 users on a single multi-user PC or running 10
stand alone PC's. Just make sure to connect the host to the LAN with the proper allowances for
multiple users to your broadband services.
Topology
As mentioned topology of a U170 environment is very important and can be impacted by the
items mention above; therefore we are providing the following topology check list:
Enough CPU power to run your desired number of video streams
Host
Two USB buses if >4-5 users running video simultaneously
Make sure there are no more than 5 hops in the topology
USB Compliance
Maximum distance is 5 meters per hop
You will need to add powered U SB hubs to add extra USB ports
downstream of the U170 as the U170 automatically assigns most
Extra USB Ports
downstream devices to the U170 session.
There can be no more than one U170 device per USB port (and each
port must support the specified 500mA of power). Use only powered
Power
USB hubs.
Cables
Use quality cables
Using quality cables don't exceed more than 5 hops on a single USB
port
Distance
