A couple of posts ago, I pointed out that we wouldn't be able to keep measuring adoption rate by the number of unique visitors in a semester, because once that number is roughly equal to the number of potential visitors, it doesn't work as a gauge anymore.
Concurrent sessions is a number that’s going to have more legs. Before the start of this semester, we had never cracked 100. My eyes bugged out at 400, but it continues to slowly rise. We hit 700 today for the first time.
The JVMs have become a lot more stable, but not immune from crashing. I guess the faulty network hardware was causing many of them. I am in the dark as to what factors remain dangerous to our JVM.
