Obviously it’s going to depend on your server, network, and local computers. In our environment, with 1 GB network, a pretty decent server, and overclocked PCs with solid state drives, running from the network typically adds about 10 seconds to the startup time.
Creo Startup Time (time from launch until the Windchill login dialog appears)
Local: 5 seconds
Network: 12-15 seconds
Running from the network basically means copying the xtop.exe file across the network and loading it into memory. As of Creo 3 M030, this is 241 MB in size.
Once Creo is loaded and running, I have been unable to distinguish any real performance impact from running across the network. Here are some older results from my testing with the OCUS benchmark. (These are not exactly “apples to apples” because several things are changing at the same time, but it does show the relative similarity.)
