scaling up

[rubing]

I have just launched my web application and am afraid of not being able to handle my traffic, b/c I have a potentially big client  .  My application is a flash mp3 player.  Basically I query mysql with php for the mp3 file and then play it using the flash mp3 player.  I may have thousands of people listening to these mp3s and am afraid that apache/mysql will be overburdened. 

 

Is streaming an mp3 file like this a huge burden on apache?  I am going to start reading a book on apache, but may not get to know enough in time.  What do you reccomend doing if I need to scale up fast.  I was thinking of buying more ram and hiring a freelancer to optimize apache & mysql.  Any other hints?? suggestions?? ideas?  insults?? 

 

 

Thanks!!!
