--- Comment #17 from Kevin Suo <suokunlong at 126.com> ---
My feeling is that there are 2 areas which makes this slow:

1. The search/sort logic may be slow and thus return the result with a delay.
This can be seen if we type in one single char in the search box.

2. The type-and-see logic, without setting a wait time before the input is
accepted as search string. For instance, if I want to search for records
containing string "abc", I would type these three chars one by one, so if the
program does not wait for (1s?), then it will try to search each time the key
is pressed, which is of cause a waste of time and CPU. Another choice is to add
a "OK" button and only start search if the button or ENTER is pressed.
