Description ehucka 2004-06-11 12:04:58 UTC

When the JDK's and projects' classes are reparsed
a displayed progress bar spends most time in its
first few percents (about 20).

I think linear dependencies are better for a man.

Comment 1 Pavel Flaska 2004-06-11 12:15:23 UTC

It is not intentionally exponential. Progress bar is based on
classpath roots count. So if you have root with a lot of classes, its
scanning takes more time, but on progress bar, every classpath root
takes the same portion.

Comment 2 ehucka 2004-06-11 12:28:29 UTC

It would be better if each class(source file) takes the same portion.
A user cannot estimate whole time of parsing. Then, there can be only
hourglass.

Comment 3 Pavel Flaska 2004-06-11 12:38:34 UTC

It is impossible without huge performance impact. You have to count
the number of scanned files before you start. It is many I/O
operation. (in WinOS they improve their time estimates throughout the
copy operation too.) I do not think this is a big problem. If you do
not think so, reopen it.
