Originally vanilla logic is to use stream, and Mojang switched it to Guava's Collections2 since 1.21.4. It is much faster than using stream or manually adding to a new ArrayList. Manually adding to a new ArrayList requires allocating a new object array. However, the Collections2 lazy handles filter condition on iteration, so much better.

Subject: [PATCH] Rail Optimization: optimized PoweredRailBlock logic
|
|
|
|
Original project: https://github.com/FxMorin/RailOptimization
|
|
|
|
Full Rewrite of the powered rail iteration logic
|
|
that makes powered/activator rails turning on/off up to 4x faster.
|
|
This rewrite brings a massive performance boost while keeping the vanilla order. This is achieved by running all the
|
|
powered rail logic from a single rail instead of each block iterating separately. Which was not only very
|
|
expensive but also completely unnecessary and with a lot of massive overhead
