Few tech companies have been hotter over the past year than Akamai Technologies Inc. (AKAM

The Cambridge (Mass.) company, which employs complex math equations and thousands of scattered servers to ship packets of data efficiently to Web surfers, saw its sales explode by 56% in the second quarter. Sales should top $400 million by the end of the year. The company is almost obscenely profitable, with operating margins of more than 30%. Its stock has tripled, to about 43, over the past year.
