Performance Problem with FastListView #2
Description
Hello,
are you able to resolve the scrolling performance issue mentioned in these threads ?
Your FluentListView suffers from the identical problem.
https://sourceforge.net/p/objectlistview/discussion/812922/thread/1d466b3b75/
Test case : FastListview : 10 text columns, 1000 rows with a hardcoded most simple aspectgetter - a simple string
To create the Problem - Hold the Keyboard down arrow and watch what happens in Task Manager when the control needs to scroll. CPU Time maxes out on the main UI thread. The videos in the link above show the problem as well. Scrolling goes lines by line and UI Thread is locked so bad that no other meaningful operations can be performed when the down/up arrows are pressed and the control is scrolling.
Try the same with 20 columns and the control becomes unusable and is anything but "fast"
Try disabling all columns (hide) and leave only the first - scroll now...that is the desired scroll performance.
I am willing to make a donation to the Person/Team that can make a super responsive FastObjectListview (using the base ObjectListview 2.9.1+ code/features) that has no scrolling problem with 20 columns
Thank you kindly
