Description oyviste 2013-10-30 09:57:43 UTC 
After resuming laptop from suspend, Netbeans notifies me of detected slowness lasting thousands of seconds. It's of course a false positive. Likely caused by suspend/resume with presumably a sudden time warp in system clock.

To reproduce, one must suspend machine with Netbeans running, for longer then some threshold in Netbeans for slowness detection, I guess.
Comment 3 Jaroslav Tulach 2013-11-26 13:54:45 UTC 
Tomáši, possibly you could compare the number of seconds with the number of obtained snapshots - if there is no correlation, then ignore the report, right?
Comment 4 Tomas Hurka 2015-07-09 13:44:30 UTC 
There is a build-in logic, which prevents taking slowness report if the sampled data are not regular enough. This should cover also suspend/resume. I am not able to reproduce it in current dev. build, so closing as works-for-me.
