In case anyone cares about stuff like this, here's how things performed yesterday.
Server load (number of processes waiting in queue):
I don't have any historical data from the old server, unfortunately, but I'm told that last year during games this graph would have been well above 4.0 the entire time. Not to mention that the new server has a dual-core processor (I think anyway), so it can handle higher loads without croaking.
This one just tells how long it takes the server to respond to a generic request, but isn't that useful it determining actual response of the Planet, since that depends a lot on the database response time, too.
Lounge HTTP response time:
This one is probably the most meaningful. This is how long it took to actually load the Lounge. However, this is probably much faster than it happens for the average user due the fact that 1)most of our network connections aren't near as fast as the service I used to generate these graphs and 2)it doesn't load any graphics at all; it just transfers the raw HTML from the page and times how long it takes to get it.
Overall, it looks like the server got pretty stressed at times, but the actual response time didn't take a hit at all. Oddly, response time was pretty slow for around 20 minutes this morning between 7:45 a.m. and 8:00 a.m. CDT. Not sure about that one, but it doesn't seem to be load-related.
Anyway, just thought some of you might find this type of thing interesting.
