At the time this was re-added, there was concern around how the JIT would handle the system property that enabled it. This shouldn't be a problem, and as such we no longer need to block access to it. The Vanilla Method Profiler will not provide much to most users however there is no harm in providing it as an option. For most users, the recommended and supported method for determining performance issues with Paper will continue to be Timings.

Subject: [PATCH] Disable Explicit Network Manager Flushing
|
|
|
|
This seems completely pointless, as packet dispatch uses .writeAndFlush.
|
|
|
|
Things seem to work fine without explicit flushing, but incase issues arise,
|
|
provide a System property to re-enable it using improved logic of doing the
|
|
flushing on the netty event loop, so it won't do the flush on the main thread.
|
|
|
|
Renable flushing by passing -Dpaper.explicit-flush=true
