which CDN plugin?

I have a large WordPress site, which was just moved to a new VPS server (my first VPS – it’s managed, because I don’t know how to run a server).

The hosting company tells me that they have a CDN installed on the server and it’s available for me to use if I’d like to enable that feature. It sounds like a good idea.

So, I did some research – a day’s worth of Googling, reading forums, etc. – and just wound up more confused about how to make the CDN work with WordPress and what plugin to use.

Several things I read suggested using W3 Total Cache – but I don’t want to do that as W3TC slowed by site down considerably.

If anyone could give me any pointers on how to decide – or suggestions on a good plugin I’d be really happy to hear them. Thanks so much!

all best,
Denise
