Resistive Plate Chambers commissioning and performance results for 2011-2013.

Resistive Plate Chambers (RPC) performance results for the period between 2011-2013 are presented. These results include history plots for the RPC relevant variables such as: Cluster Size, Efficiency, percentage of inactive detector during operation, Rates, and Currents. RPC variables are studied as function of relevant parameters such as the averaged instantaneous luminosity of the LHC, time, and CMS cavern pressure. Results obtained with the monitoring tools used by CMS such as the Web Based Monitoring tool (WBM) are also shown. RPC Background rates measured during 2010, 2011, and 2012 are presented and compared. Preparations for the 2015 Run include the installation of a new couple of disks of RPCs in the endcap regions, results obtained during quality control campaigns for the new RPCs are also presented, these results include High voltage scans that probe the quality and standards of the RPC construction procedures, as well as tests on chamber gas leaks and current behavior for the new chambers. Basic parameters such as cluster size and efficiency are also reported for these chambers.
