Test operation of SuperKEKB accelerator had been carried out up to June 2016 from February 2016 (Phase-1). In the Phase-1, the CSS Archiver and the Channel Archiver had been operated in parallel with KEKBLog, which is the main data archiving system. The number of archiving channels is expected to increase more than KEKB. Therefore, we have carried out measuring performance in the actual high-load environment during the Phase-1 operation in order to check the effectiveness of the CSS Archiver and the Channel Archiver.
