    Description

      Tested:

      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...

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
