Request: Increase the Perm Gen ceiling

[phaed]

We are in the cusp of releasing an update to our modpack and have hit up on a snag. The default ceiling for the permanent generation of 256M on the launcher is falling short of our needs.

Our testers are experiencing sluggish performance and crashes (see below) while testing our pack through the Technic Launcher (testing through the MagicLauncher with a MaxPermSize of 512M the pack plays smoothly)

Given that adding more/bigger mods = more objects/classes fitting on the perm gen, and this being core to the Technic Platform. I would like to request one of these following solutions:

• Increase the ceiling of the Perm Gen to 512M to allow for the release of packs that require such perm gen sizes.
  

• Add a setting on the modpack edit page where pack builders can set their pack's required Perm Gen size.
  

Thank you for your consideration.

bump?

[TwoTails]

bump?

Bumps are frown aponed on this forum.

[Amaxter]

Geez, i remember when my pack would barely run on 256m because we had around 200 mods, looks like you have a similar situation here. Maybe consider lightening up the pack for people with not so beefy computers? That's what i did and I have a much bigger audience now.

@phaed for Launcher Feature Requests, feel free to make an issue on the GitHub repo. CanVox looks at that more frequently than he'll be surfing forms. He'll get notifications. I will also bump this along to him for his review and consideration.

Lightening your pack is something to also seriously consider like Amaxter suggested.

[CanVox]

This is something we can look at, but I guarantee that you can reach the 256M ceiling. Here's a tip: take everything not galacticraft and remove the UE API from it. The UE API takes up a shitton of permgen space and it will take up that space once for each mod that includes the API. You only need it once, though.

[phaed]

That is a great idea! Thank you Vox! Thank you guys for the followups
