This study challenges the notion that Serial GC is unsuitable for serious applications by comparing it to G1 GC in a real production environment. Results showed comparable throughput and better latency for Serial GC. The findings suggest that with careful tuning, Serial GC can perform effectively in production settings, questioning established beliefs.
