Subject: [PATCH] Optimize FriendlyByteBuf#writeVarInt and
FriendlyByteBuf#writeVarLong
License: GPL-3.0 (https://www.gnu.org/licenses/gpl-3.0.html)
Gale - https://galemc.org
This patch is based on the following commit:
"Reapply "Optimize varint writing""
By: Andrew Steinborn <git@steinborn.me>
As part of: Velocity (https://github.com/PaperMC/Velocity)
Licensed under: GPL-3.0 (https://www.gnu.org/licenses/gpl-3.0.html)
* Velocity description *
Inspired by the approach described at the bottom of https://richardstartin.github.io/posts/dont-use-protobuf-for-telemetry
Given that we do a lot of varint writing as well, this should provide a small performance boost for larger/complex packets whilst not regressing hard on smaller packets.
This includes a test to ensure that the behavior is as expected and fixes the initialization loop so that the correct results will be given. Much thanks to @octylFractal for acting as my duck while trying to figure this out.
