Subject: [PATCH] Configurable chat thread limit
|
|
|
|
By default, spigot shifts chat over to an unbounded thread pool,
|
|
on a normal server, this really offers no gains, the creation of a thread
|
|
on submitting to the pool on these servers eats more time vs just running it in
|
|
the netty pipeline, however, on servers using plugins which do work in here, there
|
|
could be some overall benefits to moving this stuff outside of the pipeline.
|
|
|
|
In general, this patch does two things:
|
|
1) Exposes the core size for the pool, this allows for ensuring that a number of threads
|
|
sit around in the pool, mitigating the need for creating new threads; This IS however
|
|
caveated, the ThreadPoolExecutor will ONLY create core threads as they're needed, it
|
|
just won't allow for us to dip back under the # of core threads, this can potentially
|
|
be mitigated by calling prestartCoreThread, however, I'm not sure if there is much justification
|
|
for this
|
|
2) Exposes a max size for the pool, as stated, by default this is unbounded, for most
|
|
servers limiting the size of the pool is going to have 0 effects given how fast chat
|
|
is actually processed, this is honestly really just exposed for the misnomers or people
|
|
who just wanna ensure that this won't grow over a specific size if chat gets stupidly active
