Michael, sorry for the long delay, I've been very busy at the day job lately. The server is a 2.8 GHz Intel single proc box, with only 512 MB of Ram (if I start doing larger Seam apps, I think upgrading the ram will be a big win). It runs about 30 domains of varying traffic, and handles a few thousand e-mail a day (before 10minutemail.com anyhow). It's running debian stable, using Java 1.5.0_05, postfix, IMAPS and apache 2. I have jboss running behind apache (to avoid using an off-port and to avoid using an extra IP. I have done zero performance tuning of apache, jboss, etc... During the peak load (about 40,000 unique visitors, and 400,000 pages views in one day) the site was slow but responding. I'm not 100% certain why it was slow. The load average ranged from 0.5 to 2, although was mostly in the 1.0-1.2 range. There was more CPU idle than I expected. The network wasn't even close to maxxed out. I think I pushed about 1 Mbit/sec peak, and I've pushed out a full 10 Mbit from that server before on another website. It may simply have been the high number of connections waiting to be handled that made the site seem slow, as I didn't seem to be killing the CPU. Also keep in mind that during the same period tens of thousands of incoming e-mail were pouring in, being handled, and then served out to my application over IMAPS. I'd like to see what I can do with a tuned set of apps, and greater understanding of what was slowing me down.
