Dugg Again!

Hello and welcome everybody. Browsershots is on the frontpage of http://digg.com/ again. Sorry for bad server performance, but there's just too many of you. I increased the number of server processes (MaxClients) from 64 to 192, but the status page shows that the server is still overloaded. This is the first time that the new server gets some real traffic, so thank you for the testing.
And for all of you wondering about the length of the queue: the maximum wait is now 4 hours, and if you don't change it from the default it's only 30 minutes. After that, your screenshot requests simply expire. That means that some or all of your requests will be ignored, but the queue will always be 4 hours or less.
Update: There were also some errors because the database connection limit was exceeded. I increased that from 100 to 300. Sorry for the hiccups, and thanks for your feedback.
And here's some technical background info about this onslaught:
- 30 requests per second, up to 192 simultaneously
- 300 KB per second (or 1 GB per hour), for 10 hours
- 330 screenshots per hour from 5 factories
- Server load average between 10 and 30
- 1,555,307 hits or 419,155 page views or 54,442 visits or 17 GB of traffic from 40,358 unique IPs on 2006-09-07
