I apologize for a double post we fixed the issue

We set RAM to 8gb and all the other issues we fixed and added a JVM argument for nogui suddenly we have no stutter So I have had this EXACT issue, If I run a Vanilla server there is no issue and the game runs smooth, but with adding ONLY forge it stutters for everyone on the server. this happens on 2 different machines (we transfered to a friend's to test if it was my hardware) this happens with or without optifine, regardless of number of people on the server, JVM arguments(even regardless of amount of RAM), Force threaded chunk rendering, complete fresh install of a new server both vanilla(was fine no stutter) and a forge server (this is where the problem is), deleted some [.dat] files that were corrupted for about a 30% improvement. This Stuttering doesn't seem to affect any of the following: RAM usage, FPS or TPS (all are now good after deleting problem files and other minor fixes) on either the Server or Client. Im sure its being caused by a bottle neck somewhere but we cant seem to find it and when tested on my friends newer and slightly more powerful computer and internet the problem was the same. We did trouble shooting with LagGoggles and removed all offending components to no avail.
