This says 4 weeks for SEC review:

"The SEC's longstanding target is to provide initial comments on a Form S-1 within 30 days after filing. For its fiscal year ended September 30, 2012, the SEC reported that the staff provided initial comments on all Securities Act filings (covering both IPOs and non-IPOs) in an average of 24.9 calendar days—equal to the 2007-2011 average—but slightly longer than the average of 24.4 calendar days in the preceding fiscal year."
