[update: Service is now back to normal. There was an unusual load spike that lasted about ten minutes and is now over.]
I'm the person that launched the site.
I'm running it on a shared host. I apologize for any attendant problems with quality of service. (and yes, I do see the irony :)
There is a pretty obvious fix. I'd need it switch it to a virtualized host or its own machine. Sorry I haven't done this yet. I launched the site as a hobby project.
My previous site: http://metaoptimize.com/qa/
got a large amount of visitors last week and no one complained about the load. Load randomly spiked to 60 on my shared host because of another user's job.
OSQA devs tell me that running OSQA on its own machine gives very good performance. Even the largest OSQA site, like LockerGnome (http://lockergnome.net/) supposedly only has a single digit CPU percent usage when run on its own machine.
