Scaleability of MODx

Hey
We use MODx in house for all our web projects at Net Resources and had a recent pitch where the client expressed concern at the robustness of MODx and how many hits/visitors it can handle.
Anyone got any examples of high-volume sites that are built using MODx with approx stats on usage they are prepared to post?
Cheers,

Cole

Crickweb hosted on a Shared IIS server with OneSmartHost.
Up to 33,000 visitors per day, about 1 - 1.5 million page views per month.
180 - 240 GB bandwidth per month.
The server is actually being moved to a new data centre today, so it will be down for a couple of hours at some point!

It’s honestly completely dependent on the way you set up your servers, how you build your sites and structure things, and how your servers and environments are tuned. A 256MB VPS will be completely different than an 8-core 32GB Solid State Drive database server feeding an array of web servers running opcode caching. With Revo you can even throw in some memcache into the mix.
