horrible lags that blocks rendering

Postby SiO2 » Wed Feb 08, 2023 5:58 pm

Hi! I experience some sort of weird lags for quite a while. After consulting and debugging with my modder-friend we came to conclusion that they happens when pool of defer-workers gets overflowed sometimes and, due to my too good PC (24 threads) big pool makes a total mess. Temporally I hardcoded "maxthreads" down to 6 and it solved the issue made game bearable. However I think I should draw some attention of developers over there. I know, there might be no elegant solution, but please fix it if possible.

Is that a thing in the official client / ender or in another client?

I use Nurgling. However those lags are observable on official client as well. Mentioned above piece of the code belongs to the core client.

Yeah, it rarely makes sense to use all available cores, at least for latency-sensitive workloads, since even a single background process using a CPU core can throw off things significantly. Using the HT cores can also do more harm than good for certain workloads.

So
Code: Select all
private final int maxthreads = Math.max(2, Math.min(6, Runtime.getRuntime().availableProcessors() / 2));

may be a decent compromise.
