BUGs (or design flaws) that exist in Windows 10 systems cause the Jump List on the taskbar to become a little slow on some PCs. This feature has been introduced into Windows 10 systems since Windows 7 and provides access to frequently used items when the user right-clicks the icon on the taskbar.
For example, when you right-click the Chrome or Edge browser on the taskbar, you’ll find recently opened pages, frequently visited websites, and options to close your browser window. If you look closely at the animation of the right-click menu in the taskbar, you will notice a delay of 200-250ms before the menu appears.
Bruce Dawson, a Google engineer, points out that he observed this behavior on a device with 32GB of memory and 2TB SSD. “It goes far beyond the ideal time for human interaction and is a constant frustration,” he says. I don’t want to wait for my computer, especially when doing simple and repetitive actions, which I know should be able to do at about ten times the speed.”
The delay in the Windows 10 jump list occurs on all applications. Bruce explains: “The focus from the mouse launch event to ShellExperenceHost.exe is approximately 120 milliseconds. From the change in focus to the large peak of GPU activity, I believe this means that the menu is rendered approximately 110 milliseconds, so the total delay is 230 milliseconds in the particular event I’m working on. This is fairly consistent in the case of multiple traces, multiple clicks on the same entry, etc.”
Bruce also points out that the Windows team can work on many things to address the performance of right-click taskbar entries. Fortunately, the BUG report has been taken seriously by Rich Turner, Microsoft’s senior project manager. Microsoft’s product team is currently investigating the report and will share its findings soon, according to Rich Turner.
