[SelfCheck]

My team runs a site that gets a large amount of traffic per day were talking 100k visits, now we have a dedicated server for this site although the site runs fast and smooth, when we get around 600+ clicks per minute to our site it starts to timeout/load slow.

We believe it could be CDN,

anyways to solving this solution?

What CDN do you use? What are you distributing via CDN? You should only use the CDN for static content usually.

... AND ... what is your monthly bandwidth quota... may be think of upgrading it.
