Hey,
I operate Omegle (http://omegle.com/), which is a COMET-driven Twisted.Web app. (It doesn't use Nevow or anything; just Twisted.Web.) It gets fairly heavy traffic; right now, it peaks daily at around 6500 concurrent users. Technical details:
You should write a success story! I've used Omegle when the boredom hits hard.
- Hosted on a Linode 2880 virtual private server (https://www.linode.com/); Ubuntu, 2880 MB of RAM, 4 cores available - EPollReactor
Omegle currently runs at close to 100% CPU for most of the day, and I'm a bit concerned about that.
Try use the standard reactor instead of epoll. I found a similar problem when I switched my product to the epoll reactor, the cpu usage problem went away when I reverted back to the normal reactor.
