After an initial pilot run in Decomber 2009, the LHC started its first 2 year long run at 3.5 TeV beam energy end of February 2010. The performance target for those 2 years are a luminosity above 1E32 cm-2s-1 and an integrated luminosity in 2011 of 1 fm-1. To achieve those targets the LHC beam intensity and stored energy have to be pushed well above what is presently achieved at the TEVATRON in less than one year. Given the very large amount of stored energy in the beams, the intensity was ramped up progressively over a period of roughly 6 months to ensure proper protection of the accelerator. This presentation will outline the commissioning strategy of the LHC. The performance achievements and present limitations will be discussed, and the expected performance of the LHC for 2011 will be presented.
