MicroStream vs. JPA:
An Empirical Investigation

This work empirically assessed the performance of MicroStream by implementing two applications. The first one is a modified version of MicroStream’s BookStore performance demo app. The second app is an OLTP system based on the TPC -C benchmark specification. Furthermore, the authors implemented concurrent data access by using an approach based on structured modeling to handle lock granularity and deadlocks. The results show that MicroStream is up to 427 times faster when comparing the service execution time on the server with the fastest JPA transaction. From a user’s perspective, where network overhead, scheduling etc. impact the overall server response time, MicroStream is still up to 47% faster than a comparable JPA-based solution.
