> 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-1.0/compose/Server/x86_64/os/)
> 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...
