Putting a build together for a new machine and having performance problems when the client loads.  Currently it 'hangs' toward the end on reloading model (factory I think).  It does actually recover and then the game runs totally fine with no performance issues whatsoever, even with shaders turned on.  This hang though lasts about 5 minutes, which is pretty damn annoying. 

 

My machine is extremely beefy (i7, 8 core, 32gig).  I set up forge to run with the following profile:

    "Forge-1.10.2": {

      "name": "Forge-1.10.2",

      "lastVersionId": "1.10.2-forge1.10.2-12.18.1.2011",

      "javaArgs": "-Xmx4G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn4G"

    }

 

It chews through the memory (I was playing with the min value so I kind of expected that).  I could set the min back to 128 and bump up the max as I have mem to spare but I was curious as to why it might be doing this.

 

I'm using a combination of ConquestReforged, Optifine and Sildur's Shaders but the same combination on my older machine seemed to have no problems starting up. 

 

Any help would be appreciated. Thanks!

That's what I guess and I can change that easy enough.  However, still looking for the solution on the bigger problem on why forge takes 5 minutes to load model factory.

Gotcha.  4G max and 128M min then.  I'll give it a try when I get home.

For reference, there is no min, -Xms is the starting allocation, so if you set -Xms4G your OS will preallocate 4GB for the JVM that other programs cannot use (or something like that, my knowledge of this is not as good as diesieben's is)

Thanks for the clarification guys.  Didn't get a chance to try the change (wasn't home last night) but I'll mess with it tonight.
