I don't have a solution but since my problem sounds similar, I thought it would make sense to tag on to this thread.
I am using QTP and find that running the same set of tests on a new machine (that has better resources) runs slower than an older machine. I'm quite stumped and would appreciate any input on this topic. Here are some details
Parameters
Old Machine
Win XP
2GB RAM
Time to run 50 scrips End to End: 6hrs and 18 minutes
New Machine
Win 7
8GB RAM
Time to run 505 scripts end to end: 9hrs and 35 minutes
In addition all QTP patches are up to date on both machines. I am running QTP 11.0 on Windows
The application we are testing runs in the IE browser. The browsers are marginally different but I doubt that will affect performance like we're seeing here. Browser details are
Old Machine: IE 8.0.6001.18702CO (32 bit 128bit cipher strenght)
New Machine: 8.0.7601.17514 (64 bit with 256 bit cipher strength)
