As the world’s only high en­ergy po­lar­ized pro­ton col­lider, the Rel­a­tivis­tic Heavy Ion Col­lider (RHIC) at Brookhaven Na­tional Lab­o­ra­tory (BNL) has been pro­vid­ing col­li­sions of po­lar­ized pro­ton beams at beam en­ergy from 100~GeV to 255~GeV for the past decade to ex­plore the pro­ton spin struc­ture as well as other spin de­pen­dent mea­sure­ments. With the help of two Siber­ian Snakes per ac­cel­er­a­tor plus out­stand­ing beam con­trol, beam po­lar­iza­tion is pre­served up to 100~GeV. About 10% po­lar­iza­tion loss has been ob­served dur­ing the ac­cel­er­a­tion be­tween 100~GeV and 255~GeV due to sev­eral strong de­po­lar­iz­ing res­o­nances. Mod­er­ate po­lar­iza­tion loss was also ob­served dur­ing a typ­i­cal 8 hour physics store. This pre­sen­ta­tion will overview the achieved per­for­mance of RHIC, both po­lar­iza­tion as well as lu­mi­nos­ity. The plan for pro­vid­ing high en­ergy po­lar­ized He-3 col­li­sions at RHIC will also be cov­ered.
