Hmm it'd take forever to dig into the respective documentation at AWS and GCP, but from a quick look the CPU frequency alone is quite different (3.0 GHz for AWS's Xeon Scalable and 2.0 GHz for GCP's Xeon Scalable), and we don't know anything about CPU cache sizes, etc. etc. That's problematic to start. Then we have very little info to go by on the underlying storage performance. More problematic, I don't know how large the working data set is for TPM-C (i.e. how many warehouses are being simulated?), so I can't tell how much of the storage is being used. I assume it's larger than the 60GB of DRAM offered on the GCP instance (thus spilling into the storage), but with the CPU differences and unknown storage performance, I don't know what to make of this report. |
