View Full Version : [all variants] Experience Lag on Thinkpad W520 Core i7

July 15th, 2011, 07:39 AM
I have a new Thinkpad W520 Core i7 and experience that there is somehow a lag it seems.
I first realized it, when I am running Cucumber tests that previously took ~20min (and for all other devs take this long) and on my freshly installed Kubuntu 11.04 64bit takes 117 minutes.
In the meantime I realize that the applications sometimes won't react for 1-few seconds when I switch between them.

I looked at iotop and cannot see lots of activity there. I have 12GB of Ram and only ~5Gb used. When I run the test only 1-2 show high activity.

I read something about Sandybridge not beeing well supported on Kernels < 2.6.39 so I upgraded to this one:
