Issue Description After updating spongeforge from RC3900 to RC3909, lag is reported in console. According to profiler, PhaseContext.close is taking 25% of CPU. TileEntityTickContext.source is taking 10% of CPU. checkIfTileHasActiveChunk is taking 5% of CPU. It could be related to players using WarpDrive force fields (i.e. lots of tile entities).

Need a yourkit or visualvm profiling doc. The spark profiler doesn't provide enough information for me to point where there's potentially problems.

I was able to grab a short profiling while the server is frozen in that PhaseContext.close() call: image That's in SMP with SpongeForge: 1.12.2-2838-7.1.7-RC3924 Minecraft Forge: 14.23.5.2836 JVM: 1.8.0_212/64-bit (Oracle Corporation) OS: Linux (3.14.32-xxxx-grs-ipv6-64/amd64) I suspect it happens when a force field collapse (removing lots of tile entities in a single tick)
