This work started in the context of NSLS2 project at Brookhaven National Laboratory. The NSLS2 control system foresees a very high number of PV variables and has strict requirements in terms of archiving retrieving rate our goal was to store 10K PV sec and retrieve 4K PV sec for a group of 4 signals. The HyperArchiver [1] is an EPICS [2] Archiver implementation engined by Hypertable, an open source database whose internal architecture is derived from Google s Big Table. We discuss the performance of HyperArchiver and present the results of some comparative tests
