Hi guys,
My t420s sometimes gets really slow, and I would appreciate if you can help.
After upgraded to win 8, my t420s (2 cpus 4 cores) sometimes gets really slow (and hot).
If I check the task monitor, it is the system that uses about 30% of CPU. Though there is still 70% CPU left, everything becomes really slow and non-responsive.
I collect some data and upload the etl file in the following links.

In the first one, we see the system usage shoots up for now reason at the last part of the test.
In the second file, I was running some Fortran code, called Ramsey_SteadyState.exe which reasonably takes some CPU, but system also takes a lot of CPU for the whole test.
Thanks for the help!
