IP/IP and IPX/IP Gateway
Tests where conducted using a program written by Novell called Charlotte.
Charlotte uses
Netscape Navigator to access a user-determined list of URLs. This provides for simulation of real
Web usage.
After 12 hours of continuous testing there where no dropouts on the IPX / IP gateway and
6
occurred on the IP / IP gateway.
The dropouts on the IP / IP gateway can be attributed to Netscape
Navigator’s, not the gateway itself.
During the test, average server utilization was 5%.
VPN
VPN tests were conducted using NetBench® 5.01 (A Ziff Davis program which simulates normal
network traffic)
1.
With VPN enabled, the throughput decreased by 46%.
2.
Processor utilization never exceeded 25% throughout the test on both the ProLiant 6000
(Master VPN) and the ProLiant 800 (Slave VPN).
3.
The encryption process causes the decrease in throughput.
Encrypted data is larger than its
non-encrypted source, which causes the available bandwidth to be saturated quicker.
However, this is a small price to pay considering the cost savings on dedicated lease lines.
4.
We feel that the performance of VPN is comparable to other similar products.
Comparison of 10 Mbps Shared and 10 Mbps Switched
Moving from a 10 Mbps shared Ethernet at the clients to 10 Mbps switched Ethernet improves the
performance by as much as 142%.
Novell engineers were doing a separate test on a 100 Mbps Ethernet network and from the results,
it can be expected that the performance will improve by at least 200%.
Comparison of 10 Mbps Switched and 100 Mbps Shared Network
Testing by Novell Engineers has shown that changing to a 100 Mbps network will further improve
the performance by about 200%.
There was an average 92% increase in requests per second using
an equivalently configured ProLiant 6000 on a shared 100 Mbps network compared to a ProLiant
5000 on a 10 Mbps switched network.
Throughput increased by an average of 111%.
