Characterizing Transactions with Data Transfer on Multi-server Systems

摘要

In this paper, we propose an extension to our previous MVA based methodology for estimating performance of transactions executed on multi-server systems to transactions involving variable data transfers. The extension is based on the characterization of data transfers between servers under zero-load conditions, and a curve fitting step to capture server message processing time dependency with the size of the data transferred. We illustrate the extended methodology on two prototype multi-server systems.
