Im wondering if anyone would be able to help me out?
Ive been following the guide at:
I run this code, and let it finish.
xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP
I then run this code to create a summary.xml file
xperf /tti -i standby_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_sleep.xml -a suspend
which always results in this error message and an empty .xml file
C:\Temp>xperf /tti -i standby_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_sleep.
xml -a suspend

I read somewhere you may need to increase the pagefile size, which I have done, increasing it from 2047 (Windows default) to 8192 - this made no difference. I also read that you need to turn UAC on (I had it off at first), but this also made no difference for me. I also read you may need to increase buffer sizes, but I dont know how to do this? I am running on a Crucial 64GB Real SSD, connected to SATA 6GB connection using AHCI.
A brief history:
I am trying to locate what is possibly causing my PC to be slower at sleep/startup than it should be. After a lot of faffing around and getting nowhere I have done a complete reinstall of windows 7 x86 Enterprise and just have the bare essential drivers installed - LAN, Audio, AHCI, ACPI and nVidia graphics card drivers (all the latest drivers). In this configuration, I timed my sleep/resume times (using a goold old fashioned stopwatch!) and found that my sleep times were averaging 12-15 seconds (Hybrid sleep) and my resume times were 5-7 seconds. This is what I am using as a benchmark for future tests.
Now I install my TV card (Blackgold BGT3595) and as soon as I install the drivers for this card (latest drivers from manufacturers website) I see a delay in my sleep/resume times. Sleep times are now 17-31 seconds and resume times are 12-21 seconds - a big difference in comparison to the times before these drivers where installed.
I would really like to have the summary .xml file for me to identify exactly where the problems lie, and also so I could use as evidence to provide to Blackgold incase it turns out it is deffinately related to thier drivers, then the information in the summary .xml file could be of use to them in determining where the problem lies, and hopefully coming up with a solution.
The .etl file that is generated is 779MB and would be too large (I think) to send to them so the summary.xml file is my best bet I think, but as I say above, I cannot create the summary .xml file for some reason.
I can open .etl file and view the contents, but I have no clue in what I am doing and how to interpret the information displayed to me.
I can provide a quick snapshot here of Driver Delays, does this look normal or wrong ?
Also, on a side note, I noticed in the power settings where you can define what the power buttons do, before I installed the TV Card drivers I had a "Power Button" option, but after installing the drivers I had a "Power Button" and "Sleep Button" options. I found this a little confusing I just thought I would mention in here for consistency.
Thanks in advance for any help!!
