Quote from: Coldblackice on August 01, 2013, 11:50:58 AMHow can I gauge what's killing my system's responsiveness? I keep getting system-wide micro-"hangs", where everything will hang for 2-4 seconds, before resuming and quickly catching up. This is continually happening, with no apparent source or cause. What's odd is that even during hangs, mouse cursors in programs continue to visually blink as if they're unaffected by the hangs. But input definitely hangs, however -- if I type out a sentence, it will look like nothing's being input as the cursor just blinks, but 3-4 seconds later, everything gets rapidly typed out to "catch up".I've scoured Windows 7 task manager, looking for rogue programs that are eating up mass CPU or memory, but there's nothing unusual! CPU usage hovers between 1-5%, with only 4GB out of 12GB RAM used. I've also closed most programs manually, but it still happens.Now the clincher -- in Process Lasso, each time a micro-hang happens, the "Responsiveness" graph drops way down. So Process Lasso can see that the system is somehow choking --How else can I determine what's causing the system responsiveness to drop like this?How exactly does Process Lasso measure system "Responsiveness"? Perhaps knowing that will help trace to the source of this issue.
Quote from: What does the system responsiveness metric indicate?It represents the ability of the thread messages subsystem to keep up with thread/window message demand. The exact way we calculate this we don't publish, but its a pretty simple and accurate measurement.

Quote from: Official Support on August 04, 2013, 12:16:02 PMI've always wondered how often this might occur. It'd be interesting to see if one can bend cables and artificially create disk slowdowns due to SATA bus transmission errors.
