Friend and I decided to download a little modpack, and having a laptop with no use, i decided to self host for us to play.
We started with a Forge modpack, and now moved to a Fabric modpack (we are currently playing Aged).
Spark claims the TPS is at a high 20/20, and we cannot identify any modpack to be bringing any sort of lag/tick freezes.
I've currently allocated 6gbs of RAM to the server, running on said laptop with a Ryzen 7 5800H.
The lag seems to happen at any time really, even when both of us are idling/jumping around in the same chunk (at our base). it tends to be minor rollbacks that can happen every few seconds to every few minutes purely at random, in both frequency and duration.
I'm a bit lost as to what could cause any issue in the slightest. Laptop isn't running anything besides that server, and i refuse to believe a R7 5800H (4.00GHz) struggles that bad to load 2 players with a 8 chunk sim/view distance opening a chest or just jumping about.
Console never mentions anything besides the occasional 'Moshi moved too fast!', very rarely
any idea what i could do to try and diagnose the issue further/fix it ?
