MicroStream vs. JPA:
An Empirical Investigation
This work empirically assessed the performance of MicroStream (now EclipseStore) 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. The results shows that MicroStream is up to 427 times faster
