Jiefu, I agree with you. I checked the hardware specs of my machines, each one of them has:
RAM 256GB ECC Memory (16x 16 GB DDR4 1600MT/s dual rank RDIMMs Disk Two 1 TB 7.2K RPM 3G SATA HDDs For the throughput versus stored data test, it uses 5*10^10 messages, which has the total volume of 5TB, I made the replication factor to be 3, which means the total size including replicas would be 15TB, which apparently overwhelmed the two brokers I use.
