scmplayer.net this website basically allows ppl to generate a script to put my music player into their weblog.
The number of weblogs installed my music player have been rapidly increasing (right now like 300000+ sites), which is not capable to be handled by a single VPS using Apache. The traffic is concentrated in US and Brazil, so a CDN deosn't seems to be needed.
Right now I place the music player into 3 servers, which the traffic is split into 3. But having 3 servers for a simple PHP script doesn't worth it, instead optimizing server for such usage would be better.
Nginx seems to be an interesting option, I will definitely look into that. Thanks!
I can agree about suggestions related to Litespeed - it is super fast servers.. I am very pleased running my web sites at this server. BTW, I am with gigapros.com - it has litespeed and nice VPS hosting deals.. it can be a good option for you OP.
I started this thing in a shared hosting, until getting 15GB+ traffic per day, crashing their server and quickly got suspended.
Now even my VPS find difficult to handle it, I bet I am not good at optimization. So I try to ask for some advises.
Separating static content into CDN seems to be a good choice too.
