I know, also working with Rails but couldn't miss it :D
No worries, your joke gave me a chuckle too.
Looks like my wp-super-cache plugin is not working properly so every time the page is requested it regenerates the cache. No idea why but its pretty much killing the server.
I thought I had wp-super-cache enabled but maybe not. I'm giving it a reboot now so we'll see if that fixes things.
