P6 Professional clients are connected through a high-speed LAN (100 Mbit/s) to P6 Compression Server. Shunra CloudTM was used on each client in order to simulate different network conditions. P6 Compression Server is connected directly with the database server without any network layer in between.1 To do so, we use a Windows PC with two network interface cards (NICs): one connects the client machines to P6 Compression Server and the other connects P6 Compression Server directly to the database server. This two-NIC configuration is detailed in the P6 Professional Compression Server Administration Guide.
Oracle tests the performance of logging in and opening projects via the P6 Professional client using one client and five concurrent clients. For larger concurrent access, we use a tool called SQLPlayer that emulates the SQL load generated by the P6 Professional application during login. Up to three iterations are performed for each configuration (Number of clients, Network conditions) except for the Slow WAN case where one iteration was performed.
The machines used had the following configurations:
Two sets of data were used to test performance:
Oracle tested a number of network conditions: high speed LAN (100 Mbps and 0 ms latency), WAN (1544 Kbps and 50 ms latency), a medium WAN (1544 Kbps and 100 ms latency) and a slow WAN (1544 Kbps and 300 ms latency). Charts 1 and 2 show login times with a large and small database for different network configurations:
