You are right that I/O is usually the first bottleneck. I assure you that being CPU bound is no picnic, not least because most optimization knowledge and experience out there relates to I/O. :) Even if you are not CPU bound, HipHop is steadily adding grown-up features to the language that make it quite nice to use, functions like mysql_connect_with_db() which save a database round-trip, and extensions like xhprof which will tell you what is actually slow. |
