eBays J2EE backend serving over 400 million transactions a day

Just saw this on TSS and was really excited to see the headline – eBays J2EE backend serving over 400 million transactions a day. Wow. This is just huge for J2EE as eBay was implemented using Microsoft technologies. In reading the TSS thread, I agree with Cameron’s comments about the real number of transactions. I’m sure there will be more to come on this.
