WE TRIED GO'S EXPERIMENTAL GREEN TEA GARBAGE COLLECTOR AND IT DIDN'T HELP PERFORMANCE

Summary from the TLDR Dev newsletter

DoltHub tested Go's experimental Green Tea garbage collector, which is supposed to improve performance by scanning objects based on their memory location to improve cache locality. Despite running comprehensive benchmarks with their Dolt database using both single and multi-threaded workloads, they found basically identical performance between the standard garbage collector and Green Tea, with no meaningful differences in throughput, median latency, or latency distribution. The results align with the Go team's own findings that most real-world applications don't see significant performance improvements from Green Tea, and if anything, it appeared to be a slight regression in garbage collection performance for their use case.
