In the BBC’s testing, they found that with NGINX as a drop-in replacement for Varnish, they saw five times more throughput.

PHK explained the cause of this is that the Linux kernel VM system performs poorly when overcomitted.

So the conclusion is, as long your malloc fits in your system memory, Varnish should be blazing fast on Linux. If you need a gigantic cache, please try FreeBSD.

I don't suppose that particular workload was very suited for Varnish in the first place, if you read carefully, you'll soon realize that most people don't have that kind of content.

I have heard from (other parts of) BBC that Varnish saved a fair amount of bacon for them during the London Olympics, obviously in different workloads.

And nobody would be more surprised than me, if Varnish was a micacle-cure for every single website in the world...

nginx as a cache is very minimal-featured compared to Varnish. If it fits your workload, great. If not, Varnish is an exceptional tool.
