The PEP-II B-Factory at SLAC has reached a luminosity of 4.6 x 10{sup 33}/cm{sup 2}/s and has delivered 94 fb{sup -1} of data to the BaBar physics detector by the end of May 2002. PEP-II has delivered over 309 pb{sup -1} in 24 hours and over 6.35 fb{sup -1} in one month. The accelerator physics issues for these performance levels include electron cloud, beam-beam effects, parasitic beam-beam collisions, and RF beam loading. Upgrades to PEP-II are underway to increase the luminosity to 2 to 4 x 10{sup 34}/cm{sup 2}/s by FY2007. The accelerator physics effects that must be dealt with during these upgrades include RF loading, multi-bunch feedback, IR beta function, bunch length reduction, and interaction region vacuum chamber upgrades.
