A full day on the new servers

A full day of operation in which a couple of bugs were pointed out and fixed, but otherwise everything ran relatively smoothly. The only outstanding problem I'm aware of is that the Account Manager had to be disabled because it needs a new index, and I have to take down the entire system for an hour to build that index.

I'm looking at the performance monitor, and it shows 184 user connections only used a maximum of 9% of the CPU resource on the application server. Very cool.

The database server is the real hero here. It is able to keep almost a quarter of the entire database in memory, so that requests for data can be served from memory instead of requiring a disk access. My list of long-running queries shows the worst offenders to be running about 12 seconds. On the old servers, there were some queries that ran for 5 or 6 minutes!

Now that I can take a few minutes to actually breathe, there are 251 cards in the queue needing to be printed and mailed. Picked a bad day to run out of inkjet ink and card stock.
