Description Antonin Nebuzelsky 2005-11-01 13:22:14 UTC 
The test case 4) from the issue 43284 should be made faster. The lastest numbers
for this test case on Dell Precision 220, PIII 800MHz, 512MB RAM, W2K are:

Showing code completion for "new " (invoked explicitly by CTRL+SPACE in opened
jEdit.java file):

5.0beta:  6641ms, 3234ms, 3109ms
4.1:      5281ms, 3688ms, 3547ms
3.6:       375ms,  140ms,   62ms
Comment 1 Pavel Flaska 2005-11-10 16:01:21 UTC 
This issue will not be fixed for 5.0. It needs some architecture redesign. (e.g.
use lazy list in completion)
Comment 2 Tomas Hurka 2005-11-25 14:02:28 UTC 
Following fix should improve computation time of "new |"

Checking in org/netbeans/mdr/NBMDRepositoryImpl.java;

Comment 3 Pavel Flaska 2005-11-25 14:07:26 UTC 
Here are numbers (Pentium III 800MHz, 384 MB, Linux).
originally: 6.936 6.992 7.007 6.917 6.918 6.938
after fix:  6.531 6.621 6.677 6.650 6.224 6.549

(We measured time of transaction which computes all the classes.)
Comment 4 Antonin Nebuzelsky 2005-11-28 13:08:51 UTC 
Cool, this improvement is very good, at least for the first invocation. I
measured the following times (see the initial comment of this issue for comparison):

trunk 200511271900: 5312ms, 3250ms, 2937ms

Seems we are at the numbers of 4.1 now. That's great progress! Thanks!
Comment 5 Jan Becicka 2006-10-26 16:28:01 UTC 
Javacore module was replaced by Retouche infrastructure. This bug is not valid
in trunk any more.
