[jbosstools-issues] [JBoss JIRA] (JBDS-4085) unresolved bundles, slow initial start up

unresolved bundles, slow initial start up ----------------------------------------- Key: JBDS-4085 URL: https://issues.jboss.org/browse/JBDS-4085 Project: Red Hat JBoss Developer Studio (devstudio) Issue Type: Bug Components: rpm Reporter: Václav Kadlčík Assignee: Nick Boldt Fix For: 10.2.0.AM3 Attachments: disable-uses-by-default.patch, restart-after-installing-m2e-wtp-jsf-stuff-from-Central.txt, restart-after-installing-m2e-wtp-jsf-stuff-from-Central_full.txt, rh-eclipse46-devstudio10.2.log.20161028-1611.txt, unresolved-max.out, unresolved-mid.out, unresolved-min.out, workspace-max.log, workspace-mid.log, workspace-min.log Tested: * rh-eclipse46-devstudio-10.2-0.20161004.2205.el7.x86_64.rpm * rh-eclipse46 Beta (http://download-node-02.eng.bos.redhat.com/rel-eng/RHSCL-2.3-RHEL-7-Beta-...) rh-eclipse46 has its own unresolved bundles (https://bugzilla.redhat.com/show_bug.cgi?id=1381820). But when you add rh-eclipse46-devstudio, the number of unresolved symbols increases quite dramatically and initial start up times also get worse. (I guess that the two problems can be connected so I file them together but feel free to split them if I'm mistaken). I'm attaching "ss -s INSTALLED" and workspace logs for several scenarios: * "min" in the name means minimal install rh-eclipse46-devstudio * "mid" is for "yum install rh-eclipse46 rh-eclipse46-devstudio" * "max" is for "yum install 'rh-eclipse46*'" - all the available RPMs, including devstudio As for start up times, it looks like devstudio adds ~80s for one particular machine (Xeon with 16 cores 2.40GHz, 16 GB RAM). For example: initial start of rh-eclipse46: 40s same as above with rh-eclipse46-devstudio: 120s initial start of rh-eclipse46* except devstudio: 50s same as above with rh-eclipse46-devstudio: 140s Roland Grunberg managed to improve initial start up times in rh-eclise46 a few weeks ago (https://bugzilla.redhat.com/show_bug.cgi?id=1362178#c17). I don't know it it helps here but I'm linking it anyway...
