  ALBA is a 3GeV 3rd gen­er­a­tion syn­chro­tron ra­di­a­tion source built nearby Barcelona pro­vid­ing ser­vice to users since May 2012. Dur­ing all this pe­riod, a Slow Orbit Feed­back sys­tem (SOFB) has been run­ning dur­ing users’ op­er­a­tion in order to de­liver a sta­ble pho­ton beam to the Beam­lines. The sys­tem em­ploys 88 out of the 104 Beam Po­si­tion Mon­i­tors (BPMs) avail­able at ALBA and 88 hor­i­zon­tal and ver­ti­cal cor­rec­tors. In ad­di­tion, since the mid­dle of the year (July 2012), the read­ing of the X-Ray BPM (XBPM) for one of the Front Ends, with a Bend­ing Mag­net as a source, has also been in­cluded in the cor­rec­tion loop. In this paper we sum­ma­rize the per­for­mance of the SOFB sys­tem. Be­sides, we also pre­sent data cor­re­spond­ing to the evo­lu­tion along the year of the XBPM read­ings for sev­eral Front Ends that have a pla­nar In­ser­tion De­vice (ID) as a source. The an­a­lyzed XBPMs are not in­cluded in the orbit cor­rec­tion loop, and con­se­quently they sup­ply in­for­ma­tion re­gard­ing the long term sta­bil­ity of ALBA Stor­age Ring.
