I upgraded the Sage servers to 5.0, and it seems that there is some sort of really bad scalability problem that I'm only seeing on sagenb.org (or more likely, is only noticeable on a server the size of sagenb.org). Some of you may have noticed that sagenb.org has been unbearably slow the last few hours. Just FYI, it will be up and down for the next little bit while I try to diagnose the problem.

Thanks,

Jason

For those interested, it seems that the web server twisted process is pegged at 100% cpu and doesn't back down. Requests seem to work, but you have to wait for minutes for a reply.
