I have a Toshiba Satellite Pro LAPTOP with a 900MHz processor (Intel) with 512MB RAM.
I have a Dell Dimension DESKTOP 800 MHz processor with 512 MB RAM.
I am running the same engineering application on BOTH of them.
The Dell system will consistently do 850,000 calculations per second.
The Toshiba will start out at around 850,000 calculations/sec and maintain that rate so long as I'm there to move the mouse pointer around every few minutes. If I don't move the mouse pointer, the system seems to enter a standby state that causes the processing to drop from 850k calc/sec down to 90k calc/sec (or less depending on how long it's been idle). The DESKTOP system does not show these symptoms so it has something to do with the laptop. I have it configured to use Desktop Power profile, do not hiberate, no screen saver, etc. None of this seems to make any difference. A friend mentioned cache, but this is not it because the laptop CAN maintain the 850k rate if I babysit it. Thanks !
