It shouldn't really..
Are you running queries in each iteration of that loop? - I ask because moons ago I had a script that would select the next item from the database in a loop and then add that info into the html. It got to the point where it would take in excess of 30 seconds on my localhost (imagine it on a live site with a few users).
Skip ahead a few months and I found mysql's logging. When I looked at it I realised why that script was so slow - over 300 queries. Naturally I tidied this up down to one query with a couple of joins and it ran in an instant. The same number of rows but smarter and quicker than previously.
Thats why I'm asking about your setup. It's only 300 loops so shouldn't take more than a few milliseconds on a 2+GHz processor.
