Description Alexander Pepin 2011-05-23 12:34:43 UTC 
Please look at performance test results on Ubuntu ( http://nyx-intel3:8080/hudson/job/cnd-perf-ubuntu-x86/lastBuild/performance ) and notice performance regressions almost in all tests since build #365 (after switching to 7.0.1)
Comment 1 Leonid Lenyashin 2011-05-23 15:36:46 UTC 
Please evaluate
Comment 2 Alexander Simon 2011-05-23 20:23:48 UTC 
Please provide steps to reproduce bug.
Comment 3 Alexander Pepin 2011-05-24 17:08:33 UTC 
It seems that the main problem is ProjectViewAfterParsing test.
Steps to reproduce:
- open a project (loki, LiteSQL, MySQL, Python etc)
- wait until the project is parsed
- expand some specific source node in projects view
Result: Previously in NB 6.9.1 and NB 7.0 it took < 0.5 sec. and now it takes > 2.5 sec.

Definitely it is not P2.

Paths to folders for test projects:

clucene.folder=clucene-0.9.10/src/CLucene/search

litesql.folder=litesql-0.3.1/src/library

boost.folder=boost_1_36_0/boost

loki.folder=loki-0.1.5/src

mysql.folder=mysql-5.0.18/sql

perl.folder=perl-5.8.5

python.folder=Python-2.4/Modules
Comment 6 Quality Engineering 2011-05-26 11:22:10 UTC 
Integrated into 'main-golden', will be available in build *201105260401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Comment 7 Alexander Simon 2011-05-27 07:48:24 UTC 
It seems benchmark ProjectViewAfterParsing is wrong.
It measures random noise with 2 seconds.
For example results for boost:
NB6.9	283
NB7.0 	387
b365	414
b366	2267
b367	263
b370	292
b371	336
b372	2177
So you can see that builds b366 and b372 contain a 2 second noise.
Please fix your benchmark ProjectViewAfterParsing.
Or compare separately measurements with noise and without noise.

By the way the noise is not reproducible manually.
Comment 8 Alexander Pepin 2011-05-27 09:25:58 UTC 
Please be careful with your definitions. It's not a noise as the overall performance index for ProjectViewAfterParsing shows the regression. It's probably not a regression in CND part of NB but something is definitely prevents ProjectsView from working faster.

BTW MySQL gives:

NB 6.9.1    361
nb 7.0      763
#365       2806
#366       2893
#367       2740
#370       2725
#371       2673
#372       2921
#373       2702
#375       2644
#376       2656
Comment 9 Alexander Simon 2011-05-27 12:31:39 UTC 
issue is not reproducible manually.
