Installing windows 7

For some time I've been messing around with different settings, drivers etc. in my Bootcamp windows XP partition. Actually so much that I don't know what's up and down anymore. So the first step is to start with a clean install. And why try to make things work in XP if they'll work out of the box in win 7. So setting up a win 7 Bootcamp partition.

Checking tahe system response with DPClatency

Just after installing win7 I have a small spike between 800-100 mysec every 15 seconds. Occasionally there's a spike at 10620 mysec

After disabling in device manager: Bluetooth, network adapters, Audio Hardware , iSight it seems like I got rid of the biggest spikes.

Installing Bootcamp 3.0 drivers (build 2058) and apple update

• intel graphics
• ati graphics
• crystal beach
• broadcom wireless network
• sigmatel sound
• (removing old realtek sound)
• realtek sound
• usb modem
• cirrus logic
• Intel Ethernet

And a whole lot more I could'nt read.

After installing Bootcamp drivers I checked DPC latency again and found that it was all red. After killing the bootcamp.exe process in the task manager the latency almost went back to normal. But disabling audio, network etc. again optimized a little.

Installing Fireface 800 driver

I've used driver version 3.02 and firmware 2.77. I had audio going but Sequoia hangs once in a while without no obvious reason. I have to compare the hangs to the DPClatency checker to see if it occours when there are spikes.

The next thing I'm going to do is to compare the MBP performance with my good rock steady PC I build back in 2001.
