      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...
