  The CMS experiment recorded 177.75 /fb of proton-proton collision data during
the RUN-1 and RUN-2 data taking period. Successful data taking at increasing
instantaneous luminosities with the evolving detector configuration was a big
achievement of the collaboration. The CMS RPC system provided redundant
information for the robust muon triggering, reconstruction, and identification.
To ensure stable data taking, the CMS RPC collaboration has performed detector
operation, calibration, and performance studies. Various software and related
tools are developed and maintained accordingly. In this paper, the overall
performance of the CMS RPC system and experiences of the data taking during the
RUN-2 period are summarised.
